Creativity : 10 Cutest Cars & Customization Rules

Unfortunately, only a few cars made it to the roads and many of them just remained as much adored cars on Techno-Exhibitions.

Because customization of Cars has many laws associated with it and that varies from country to country. You can read some of the common illegal alterations following this gallery. So when you try customizing your car, always check your state’s law.

In India, you check the following list before you customize.

  • First, get the modification plans approved by the original car maker
  • Modify the car according to the approved plan
  • Get the modified car approved by the original car maker
  • If approved, the owner has to get the car certified at one of three government-approved certifying agencies
  • Once cleared by them, an RTO certificate will enable the owner to drive around town without being pulled up

However, these cars will tempt you at least to go for a ride. 🙂 Which one is your favourite?

10 common illegal customizations

  1. Window tinting

    Dark window tinting is one of the most common illegal alterations made to cars. Every state has different laws regarding window tinting and regulations, including light transmittance and location of tinting. Some states are stricter about tinting the driver’s side window and the windshield. For the most part, a light tint is the best way to go and will keep you out of trouble with law enforcement.

  2. License plate frames

    Customizing license plates and the frames that keep them in place is very popular. It may seem harmless to have a customized frame that advertises a dealership or your favorite sports team, but you can actually get pulled over and ticketed if the frame covers up the state name or numbers in any way. Tinted and reflective-plate covers are also illegal in many states.

  3. Exhaust

    Adding a performance exhaust to your vehicle can make it more powerful, faster, and louder than before. Drivers who install a new exhaust system may have a noisier and meaner sounding vehicle, but you’ll also run the risk of being ticketed if it’s too loud and causes any noise complaints.

  4. HID headlamps

    Drivers who want a customized look for their car might be tempted to get a HID headlamps kit to install, but this popular alteration is illegal in all 50 states. The National Highway Traffic Safety Administration says that no HID headlamps meet the federal photometric standards, so if you install these you may end up with a pricey ticket.

  5. Undercarriage lighting

    Undercarriage lighting is a popular, but often illegal alteration made to cars. Adding bright neon or LED lights may be illegal in your state, especially if it interferes with the front and rear lighting. Some states have restricted certain colors and color combinations that might cause confusion or distractions on the road.

  1. Lifts

    Lifting the suspension or frame and body of your vehicle can drastically change the way your car looks and drives. As popular as this alteration is, your state may have a limit on how high you can go. Some states set their height restrictions based on maximum headlight and taillight heights and others measure by maximum bumper heights. Depending on the state you live in or drive through, you could be ticketed for an excessive lift.

  2. Muffler delete

    Drivers who want to increase the horse power and noise level of their vehicle may consider installing muffler delete pipes. But it’s important to know that every state has different laws relating to muffler delete alterations, but for the most part, it’s illegal. Most states require all vehicles have a working muffler to prevent excessively loud or unusual noises, but adding a muffler delete or similar device to your vehicle is illegal.

  3. Studded tires

    Many drivers install studded tires to get better traction on slippery roads during the winter season, but these tires can also destroy pavement. Even though studded tires have been approved by the federal government and received the DOT rating, some states do not allow them on their roads or only at certain times of the year.

  4. Off-road lamps

    High-intensity off-road lamps are very bright and very illegal in some states. These 100-watt (or more) lights are often attached to the grille of trucks or mounted on the roof of vehicles. Off-road lamps might help you find your way through the dark wilderness, but they are completely unnecessary for everyday driving. The range, intensity, and light patterns of these lamps are extremely distracting on the road and can cause danger to oncoming traffic.

  5. Cold air intake

    This is a common alteration made to mostly muscle cars and four-cylinder import vehicles. Drivers install cold air intake systems for various reasons, but one of the most common is to produce more power from the engine. But this increase in power can result in an increase in fuel consumption and emissions. Your car may seem like it’s running better, but if you’re exceeding the legal emissions limits, you could be in trouble with the law.

Know : How Maglev Trains Work without Wheels?

Magnets always fascinate us and a favourite topic for many physics lovers. Magnets just not have the property to attract metals but also attracted the interests of modern day scientists. The principle of magnetism is been applied many utilities in our daily life.

Ever since the issue of global warming and fossil fuels popped up, the world is looking for an alternate energy. Transportation is one of the major factors when it comes to greenhouse gases.

How about using magnets for transportation? A transport without any fuel? without any emission? Is that possible?

Maglev Transportation is the first step towards a great future. Let us learn more about it.

What is Maglev?

Maglev (derived from magnetic levitation) is a transport method that uses magnetic levitation to move vehicles without touching the ground. With maglev, a vehicle travels along a guideway using magnets to create both lift and propulsion, thereby reducing friction and allowing higher speeds.

Maglev

When you were a kid, you might have tried to balance one magnet in the air using other magnets. The same basic principle is applied using electromagnetic (maglev) tracks.

The Differences

The big difference between a maglev train and a conventional train is that maglev trains do not have an engine — at least not the kind of engine used to pull typical train cars along steel tracks. The engine for maglev trains is rather inconspicuous. Instead of using fossil fuels, the magnetic field created by the electrified coils in the guideway walls and the track combine to propel the train.

How Maglev Train works

Comparison with conventional trains

Maglev transport is non-contact and electric powered. It relies less or not at all on the wheels, bearings and axles common to wheeled rail systems.

  • Speed: Maglev allows higher top speeds than conventional rail, but experimental wheel-based high-speed trains have demonstrated similar speeds.
  • Maintenance: Maglev trains currently in operation have demonstrated the need for minimal guideway maintenance. Vehicle maintenance is also minimal (based on hours of operation, rather than on speed or distance traveled). Traditional rail is subject to mechanical wear and tear that increases exponentially with speed, also increasing maintenance.
  • Weather: Maglev trains are little affected by snow, ice, severe cold, rain or high winds. However, they have not operated in the wide range of conditions that traditional friction-based rail systems have operated.[citation needed] Maglev vehicles accelerate and decelerate faster than mechanical systems regardless of the slickness of the guideway or the slope of the grade because they are non-contact systems.
  • Track: Maglev trains are not compatible with conventional track, and therefore require custom infrastructure for their entire route. By contrast conventional high-speed trains such as the TGV are able to run, albeit at reduced speeds, on existing rail infrastructure, thus reducing expenditure where new infrastructure would be particularly expensive (such as the final approaches to city terminals), or on extensions where traffic does not justify new infrastructure.
  • Weight: The electromagnets in many EMS and EDS designs require between 1 and 2 kilowatts per ton. The use of superconductor magnets can reduce the electromagnets’ energy consumption. A 50-ton Transrapid maglev vehicle can lift an additional 20 tons, for a total of 70 tons, which consumes 70-140 kW.[citation needed] Most energy use for the TRI is for propulsion and overcoming air resistance at speeds over 100 mph.[citation needed]
  • Weight loading: High speed rail requires more support and construction for its concentrated wheel loading. Maglev cars are lighter and distribute weight more evenly.
  • Noise: Because the major source of noise of a maglev train comes from displaced air rather than from wheels touching rails, maglev trains produce less noise than a conventional train at equivalent speeds. However, the psychoacoustic profile of the maglev may reduce this benefit: a study concluded that maglev noise should be rated like road traffic, while conventional trains experience a 5–10 dB “bonus”, as they are found less annoying at the same loudness level.
  • Braking: Braking and overhead wire wear have caused problems for the Fastech 360 rail Shinkansen. Maglev would eliminate these issues.
  • Magnet reliability: At higher temperatures magnets may fail. New alloys and manufacturing techniques have addressed this issue.
  • Control systems: No signalling systems are needed for high-speed rail, because such systems are computer controlled. Human operators cannot react fast enough to manage high-speed trains. High speed systems require dedicated rights of way and are usually elevated. Two maglev system microwave towers are in constant contact with trains. There is no need for train whistles or horns, either.
  • Terrain: Maglevs are able to ascend higher grades, offering more routing flexibility and reduced tunneling.

Comparison with aircraft

Differences between airplane and maglev travel:

  • Efficiency: For maglev systems the lift-to-drag ratio can exceed that of aircraft (for example Inductrack can approach 200:1 at high speed, far higher than any aircraft). This can make maglev more efficient per kilometer. However, at high cruising speeds, aerodynamic drag is much larger than lift-induced drag. Jets take advantage of low air density at high altitudes to significantly reduce air drag. Hence despite their lift-to-drag ratio disadvantage, they can travel more efficiently at high speeds than maglev trains that operate at sea level.
  • Routing: While aircraft can theoretically take any route between points, commercial air routes are rigidly defined. Maglevs offer competitive journey times over distances of 800 kilometres (500 miles) or less. Additionally, maglevs can easily serve intermediate destinations.
  • Availability: Maglevs are little affected by weather.
  • Safety: Maglevs offer a significant safety margin since maglevs do not crash into other maglevs or leave their guideways.
  • Travel time: Maglevs do not face the extended security protocols faced by air travelers nor is time consumed for taxiing, or for queuing for take-off and landing.

Despite decades of research and development, only two commercial maglev transport systems are in operation, with two others under construction. The highest recorded maglev speed is 603 km/h (375 mph), achieved in Japan by JR Central’s L0 superconducting Maglev on 2015 April,21. The Japanese trains use super-cooled, superconducting electromagnets. This kind of electromagnet can conduct electricity even after the power supply has been shut off.

Alert! : Time Lapse of All Nuclear Explosions on Earth from 1945 – 1998

It starts really slow — if you want to see real action, skip ahead to 1962 or so — but the buildup becomes overwhelming.

Japanese artist Isao Hashimoto has created a beautiful, undeniably scary time-lapse map of the 2053 nuclear explosions which have taken place between 1945 and 1998, beginning with the Manhattan Project’s “Trinity” test near Los Alamos and concluding with Pakistan’s nuclear tests in May of 1998. This leaves out North Korea’s two alleged nuclear tests in this past decade (the legitimacy of both of which is not 100% clear).

Each nation gets a blip and a flashing dot on the map whenever they detonate a nuclear weapon, with a running tally kept on the top and bottom bars of the screen. Hashimoto, who began the project in 2003, says that he created it with the goal of showing”the fear and folly of nuclear weapons.”

Documentary : World’s Strongest Materials

Materials science, also commonly known as materials engineering, is an interdisciplinary field applying the properties of matter to various areas of science and engineering. This relatively new scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. It incorporates elements of applied physics and chemistry. With significant media attention focused on Nano science and nanotechnology in recent years, materials science is becoming more widely known as a specific field of science and engineering. It is an important part of forensic engineering (Forensic engineering is the investigation of materials, products, structures or components that fail or do not operate or function as intended, causing personal injury or damage to property.) and failure analysis, the latter being the key to understanding, for example, the cause of various aviation accidents. Many of the most pressing scientific problems that are currently faced today are due to the limitations of the materials that are currently available and, as a result, breakthroughs in this field are likely to have a significant impact on the future of technology.
