In the vacuum suspended system, the brakes are applied when

  1. Atmospheric pressure is applied to one side of diaphram

  2. Vacuum is applied to both sides of diaphram

  3. Atmospheric pressure is applied to both sides of diaphram

  4. Vacuum is applied to one side of diaphram


Correct Option: A
Explanation:

In the vacuum suspended system, the brakes are applied when atmospheric pressure is applied to one side of diaphram.

When two cylinder with different size like larger and smaller are kept together then though the pressure is same in both, still the force required is more for larger cylinder. Due to increase in which property?

  1. Area

  2. height

  3. Weight

  4. Volume


Correct Option: A
Explanation:

Force required        $F = PA$    

$\implies$    $F\propto A$                          $(\because P = constant)$
Thus option A is correct.

In a vacuum suspended unit, when the brakes are on , the piston and diaphragm has on both sides of it

  1. Atmospheric pressure

  2. Vacuum

  3. Hydraulic pressure

  4. Air pressure


Correct Option: A
Explanation:

In a vacuum suspended unit, when the brakes are on , the piston and diaphragm has on both sides of it Atmospheric pressure.

What is a hydraulic jack?

  1. Device uses force to lift heavy objects

  2. Device uses force for pumping water

  3. Device uses force to pump air

  4. Device use to lower the harder objects


Correct Option: A
Explanation:

Hydraulic jack is a device, works on the Pascal's law, used to lift heavy objects. 

The type of braking system referred to as power brake makes use of

  1. Electromagents

  2. Compressed air

  3. Vacuum

  4. Compressed water


Correct Option: B
Explanation:

Type of braking system referred to as power brakes makes the use of compressed air.

In the hydraulic braking system , the piston in the master cylinder is connected by mechanical linkage to the

  1. Wheel cylinders

  2. Brake shoes

  3. Brake pedal

  4. Wheel pedal


Correct Option: C
Explanation:

The piston in the master cylinder is connected by mechanical linkage to the Brake pedal in the hydraulic braking system.

In the integral type of power brake , the diaphragm acts directly on the hydraulic piston in the

  1. Master cylinder

  2. Wheel cylinder

  3. Adjacent cylinder

  4. Multiplier unit


Correct Option: D
Explanation:

Since in integral type of power brake, the diaphgram acts directly on the hydraulic piston in the multiplier unit which leads to the increase in further pressure.

In the power assisted kind of brake the bellows applies force to master cylinder piston

  1. Through diaphragm linkage

  2. Directly

  3. Through mechanical linkage

  4. Through kinetic linkage


Correct Option: C
Explanation:

In the power assisted kind of brake the bellows applies force to master cylinder piston through mechanical linkage. A mechanical linkage is an assembly of bodies connected to manage forces and movement.

In Jeeps we use

  1. Mechanical brakes

  2. Hydraulic brakes

  3. Air brakes

  4. water brakes


Correct Option: B
Explanation:

Most brakes on cars now are what are called "Power" brakes, and driven by a hydraulic braking control system

In the air brake, air pressure is supplied by

  1. Engine manifold

  2. A compressor

  3. The diaphragm valve

  4. pump


Correct Option: B
Explanation:

An air compressor produces air for the brake system. Powered by the vehicle’s engine, the air compressor draws in air at normal pressure and forces it into a much smaller space, causing the pressure of the air to increase. This compressed air is a form of stored energy.
