• regulates, maximize fluctuations, min speed, load variations.

Governor is an example of

• mechanical feedforward control system which senses the output and regulates input accordingly.

• mechanical feedback control system which senses the output and regulates input accordingly.

• mechanical feedforward control system which senses the input and regulates output accordingly.

• mechanical feedback control system which senses the input and regulates output accordingly.

In a Centrifugal Governor, its action depends on

• The Centrifugal effects produced by the mass of the sleeve.

• The Centrifugal effects produced by the masses of two balls.

• The Centrifugal effects produced by the mass of the spindle.

• The Centrifugal effects produced by the mass of the valve.

Guess the INCORRECT statement

In Inertia Governor

• The movement of the balls is due to the

  rate of change of speed.

• Less sensitive to increase or decrease in

  load.

• Quick response to change in load.

• Difficult to completely balance the

  revolving parts.

Guess the INCORRECT statement

In Centrifugal Governor

• The movement of the balls is due to

  change in speed itself.

• Highly sensitive to increase or decrease

  in load.

• Slower response

  to change in load.

• Easy to completely

  balance the revolving

  parts.

It is a heavy rotating wheel that reduces the jerk due to unavoidable fluctuations of speed, is called as

• Front Wheel

• Rear Wheel

• Gyroscope

• Flywheel

A flywheel

• It keeps the fluctuation of speed of the engine within specified limits under varying load conditions due to the variable pressure

• It limits the mean speed during each thermodynamic cycle by adjusting the fuel supply

• It limits the fluctuation of speed during

  each thermodynamic cycle which occurs

  due to the variable pressure.

• It keeps the mean

  speed of the engine

  within specified limits under varying

  load conditions by adjusting the fuel

  supply.
