Power steering

Image
The term power steering is usually used to describe a system that provides mechanical steering assistance to the driver of a land vehicle, for example, a car or truck. The power steering system in a vehicle is a type of servomechanism. For many drivers, turning the steering wheel in a vehicle that doesn't have power steering requires more force (torque) than the driver finds comfortable, especially when the vehicle is moving at a very slow speed. Steering force is very sensitive to the weight of the vehicle, and nearly so much to its length, so this is most important for large vehicles. In a vehicle equipped with power steering, when the driver turns the steering wheel, she or he feels only a slight retarding force, so a vehicle equipped with power steering can be driven by any healthy driver, even when the vehicle is being parked. This is because the power steering system furnishes most of the energy required to turn the steered wheels of the car. Most power steering systems

ABS - an Excellent safety feature in many modern vehicles

Image
An anti-lock braking system (ABS, from German: Antiblockiersystem) is a safety system that allows the wheels on a motor vehicle to continue interacting tractively with the road surface as directed by driver steering inputs while braking, preventing the wheels from locking up (that is, ceasing rotation) and therefore avoiding skidding. An ABS generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces for many drivers; however, on loose surfaces like gravel or snow-covered pavement, an ABS can significantly increase braking distance, although still improving vehicle control. Stopping a car in a hurry on a slippery road can be very challenging. Anti-lock braking systems (ABS) take a lot of the challenge out of this sometimes nerve-wracking event. In fact, on slippery surfaces, even professional drivers can't stop as quickly without ABS as an average driver can with ABS. The theory behind anti-lock brakes is simple. A skidding wheel (where

Tubeless tires

Image
   Tubeless tires are pneumatic tires that do not require a separate inner tube. Unlike traditional pneumatic tires which use a separate inner tube, tubeless tires have continuous ribs molded integrally into the bead of the tire so that they are forced by the pressure of the air inside the tire to seal with the flanges of the metal rim of the wheel. Traditional designs of pneumatic tires required a separate inner tube which could fail for a number of reasons, such as incorrect tire fit, friction between the tire wall and inner tube generating excess heat or puncture. Tubeless tire technology does away with the need for an inner tube thereby increasing safety. In a tubeless tire, the tire and the rim of the wheel form an airtight seal, with the valve being directly mounted on the rim. If a tubeless tire gets a small puncture, air escapes only through the hole, leading to a gentle deflation. Conversely, an inner tube could potentially burst like a balloon, leading to a rapid deflatio

Fuel cell vehicles (FCV) - ultimate eco-car

Image
The fuel cell vehicle (FCV) is the nearest thing yet to an "ultimate eco-car" that offers solutions to energy and emissions issues. FCVs are powered by fuel cells, which generate electricity from hydrogen, which is not only environmentally friendly and highly energy-efficient, but can also be produced using a variety of readily available raw materials. Thanks to these characteristics, fuel cell vehicles are ideal for achieving sustainable mobility. Therefore, Toyota is striving to make this vehicle technology widely available as soon as possible. Successful startup: -30° Celsius Extended cruising range: 830km (JC08 mode) without refueling At a steady cruising speed, the motor is powered by energy from the fuel cell. When more power is needed, for example during sudden acceleration, the battery supplements the fuel cell’s output. Conversely, at low speeds when less power is required, the vehicle runs on battery power alone. During deceleration the motor functions as an ele

Wireless Battery Charger

Image
In the future all electronic devices will be wirelessly powered. Small, battery-powered gadgets make powerful computing portable. The battery charger should be capable of charging the most common battery types found in portable  devices today.  In addition, the charging  should be  controlled from the base station and a bidirectional communication system between  the pickups  and base  station  should be developed. Inductive Power Systems: Inductive Power Transfer (IPT)  refers to the concept of transferring electrical power between two isolated circuits across an air gap.  While based on the work and concepts developed by pioneers such as  Faraday and Ampere, it  is  only recently that IPT has been developed into working systems. Essentially, an IPT system can be divided into two parts; Primary and Secondary. The primary side of the system is made up of a resonant power supply and a coil. This power supply produces a high frequency sinusoidal current in the coil.  The seconda

The Biggest Cities in The World

This is the list of biggest cities in the World.I like big cities. I also like interesting facts, geography, and statistics. Occasionally, I wondered what the biggest cities in the world are. I found the following statistics online, from Thomas Brinkhoff, Principal Agglomerations and Cities of the World. Web: www.citypopulation.de. Tokyo Mexico City Ä°stanbul Urban Area / City Name Country Estimated population (in millions) 1. Tokyo Japan 34.2 2. Mexico City Mexico 22.8 3. Seoul South Korea 22.3 4. New York USA 21.9 5.

Chesapeake Bay Bridge-Tunnel

Image
Chesapeake Bay Bridge-Tunnel The  Chesapeake Bay Bridge-Tunnel ( CBBT )  is a 23 mile long bridge and tunnel system that connects southeastern Virginia with Delmarva Peninsula in the United States. The bridge connects the following independent cities Virginia Beach, and Norfolk, Virginia to Cape Charles in Northampton County along the eastern shore of Virginia. The Chesapeake Bay Bridge-Tunnel uses a combo of tunnels and bridges over two separated shipping channels using four artificial islands built in the bay as portals. The bridge-tunnel was opened on April 15th, 1964, in August 1987 it was officially named the Lucius J. Kellam Jr. Bridge-Tunnel after one of the civic leaders who worked for its development. However, it still is best known as Chesapeake Bay Bridge-Tunnel. The bridge part of the Chesapeake Bay Bridge-Tunnel as far as I can know is 15.6 Miles long which is why this bridge is placed at number at the worlds 9th longest bridge and 7th longest over water and 4th

Underground Skyscraper in Mexico City

Image
The Earthscraper, designed by  BNKR Arquitectura , is the Skyscraper’s antagonist in the historic urban landscape of Mexico City where the latter is condemned and the preservation of the built environment is the paramount ambition. It preserves the iconic presence of the city square and the existing hierarchy of the buildings that surround it. More images and architects’ description after the break. The Historic Center of Mexico City is composed of different layers of cities superimposed on top of each other. When the Aztecs first came into the Valley of Mexico they built their pyramids on the lake they found there. When a new and bigger pyramid was conceived and the Aztec Empire grew in size and power, they did not search for a new site, they just built on it and around the existing one. In this manner, the pyramids are composed of different layers of historical periods. When the Spanish arrived in America and ultimately conquered the Aztecs, they erected their Christian temple

The Magdeburg Water Bridge

Image
The Magdeburg Water Bridge  (German: Wasserstraßenkreuz) is a navigable aqueduct in Germany, opened in October 2003 . It connects the Elbe-Havel Canal to the Mittellandkanal, crossing over the Elbe River. It is notable for being the longest navigable aqueduct in the world, with a total length of  918 metres (3,012 ft). The Elbe–Havel Canal and Mittelland Canal canals had previously met near Magdeburg but on opposite sides of the Elbe, which was at a significantly lower elevation than the two canals. Ships moving between the two had to make a 12-kilometre (7.5 mi) detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sailing downstream on the river, before ascending up to the Elbe-Havel Canal through Niegripp lock. Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo. History Canal engineers had first conceived of joining the two waterways as far back as 1
