Explanation

1 x  1 + 1 = 2

2 x 2 + 2 = 6

3 x 3 + 3 = 12 

4 x 4 + 4 = 20 

5 x 5 + 5 = 30 

6 x 6 + 6 = 42

Explanation

The roadway would cause diffuse reflection due to its rough surface

some examples where diffused reflection

• Desert sand,
• disturbed water surface,
• and rough roads  
  

Explanation

Water body work is to cool engine.

Water of radiator circulate all side of engine just to keep cool.

Explanation

A shaft is a rotating machine element that is used to transmit power from one place to another. 

Explanation

There are two types of valves in an engine cylinder:

1. Inlet Valve 
2. Exhaust Valve.
   

Explanation

3 Piston rings as follows:

• 1st piston ring:

compression of combustion air or gas mixture and the resulting gas pressure in the combustion cycle, transfer of generated heat to the cylinder surface

• 2nd piston ring:

support of the remaining gas pressure due to blow-by past the 1st piston ring

• 3rd piston ring:

scraping of oil 

Explanation

car axles are part of the system that takes the engine's power to turn the wheels and propel the car

Axles are essential components of any vehicle and

three main types:

1. front
2. rear
3. stub
   

Explanation

Governor is the device used to control the speed of engines when there is variation in the load

speed of an engine varies in two ways

1. during each revolution or cyclic variation 
2. over a number of revolutions

during each revolution or cyclic variation the speed of the engine varies due to variation in output  torque of the engine

over a number of revolution, the speed of the engine varies due to variation in load upon engine and the speed maintained by mounting a governor

Explanation

anti-lock braking system used on aircraft and on land vehicles

The modern ABS system was invented in 1971 by Mario Palazzetti

In 1988, BMW introduced the first motorcycle with an electro-hydraulic ABS

There are  four main components of ABS:

1. wheel speed sensors
2. valves
3. a pump
4. and a controller.
