There is a lot of information regarding vehicles after all this is the single invention that has contributed to mobility in the world. We have grown from the basic need of vehicles to buying vehicles for the sake of keeping, luxury or showing off. It should not be surprising that apart from the car being the most used machine, there are several things that people still do not know about cars.
- In The USA, States Have Varying Laws On Seat Belts
Seat belt laws vary across states in America. These are split into two sections: primary seat belt laws whereby drivers and passengers can be ticketed for not wearing seat belts and secondary seat belt laws whereby drivers and passengers can only be ticketed for not wearing a belt if another traffic offense has also occurred.
- Driverless Cars Are Becoming A Reality
There are several entities attempting to create cars that can function without drivers. Google has created 10 different self-driving cars that have travelled a total of 300,000 miles on busy roads and have only resulted in 2 incidents, with one happening while a human was driving and one when another vehicle hit the car. It will be exciting to see the development of this technology and its implications on car related accidents.
Buying a car is expensive hit wonder if that lowers the rate of production of cars. In fact the car manufacturing business is booming like never before. This could only mean that no matter the price, people are still buying because travelling is not a luxury but a necessity in life.
For the first time ever annual global auto sales have topped 80 million vehicles, according to consulting firm IHS Automotive.
The firm tallied year-end sales numbers from around the world and came up with a total of 82.84 million vehicles, a 4.2% increase compared to 2012.
The sales pace means 2.6 new vehicles were sold every second last year.
Every car has its horsepower unfortunately most people do not know the right definition of that. Most of the times it is assumed that the number of horsepower amounts to the number of horses which is not the case.
The story goes that Watt was working with ponies lifting coal at a coal mine, and he wanted a way to talk about the power available from one of these animals. He found that, on average, a mine pony could do 22,000 foot-pounds of work in a minute. He then increased that number by 50 percent and pegged the measurement of horsepower at 33,000 foot-pounds of work in one minute. It is that arbitrary unit of measure that has made its way down through the centuries and now appears on your car, your lawn mower, your chain saw and even in some cases your vacuum cleaner.
Horsepower can be converted into other units as well. For example:
1 horsepower is equivalent to 746 watts. So if you took a 1-horsepower horse and put it on a treadmill, it could operate a generator producing a continuous 746 watts.
1 horsepower (over the course of an hour) is equivalent to 2,545 BTU (British thermal units). If you took that 746 watts and ran it through an electric heater for an hour, it would produce 2,545 BTU (where a BTU is the amount of energy needed to raise the temperature of 1 pound of water 1 degree F).
