Q:

Among the following which one exhibits linearly rising load torque characteristics?

A) Elevators B) Rolling Mills
C) Fan load D) Separately excited dc generator connected to the resistive load
 
Answer & Explanation Answer: D) Separately excited dc generator connected to the resistive load

Explanation: Separately excited dc generator connected to the resistive load is an example of linearly rising load torque characteristics as the torque increases linearly with an increase in speed.

Q:

Passive torques always oppose the motion of the driven machine.

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: Passive torques are due to friction or shear and deformation in elastic bodies. They always oppose the motion, restricting the motion of the machine.

Q:

What type of force handles for active torques?

A) Strong nuclear forces B) Weak nuclear forces
C) Gravitational forces D) Electrostatic forces
 
Answer & Explanation Answer: C) Gravitational forces

Explanation: Gravitational forces are responsible for active torques. Active torques due to gravitational forces can be obtained in the case of hoists, lifts or elevators and railway locomotives operating on gradients.

Q:

What is the relationship between torque and speed in constant type loads?

A) Torque is independent of speed B) Torque linearly increases with increase in speed
C) Torque non-linearly increases with an increase in speed D) Torque non-linearly decreases with an increase in speed
 
Answer & Explanation Answer: A) Torque is independent of speed

Explanation: Speed hoist is a perfect example of constant type loads in which torque variation is independent of speed. The speed-torque characteristics of this type of load are given by T=K where K is a constant.

Q:

Rolling mills exhibit what type of load torque characteristics?

A) Constant torque characteristics B) Linearly rising torque characteristics
C) Non-Linearly rising torque characteristics D) Non-Linearly decreasing torque characteristics
 
Answer & Explanation Answer: D) Non-Linearly decreasing torque characteristics

Explanation: Rolling mills are an example of non-linearly decreasing torque characteristics because torque and speed exhibits inversely proportional relationships and power are constant.

Q:

Load torques can be classified into how many types?

A) Three B) Two
C) Four D) Five
 
Answer & Explanation Answer: B) Two

Explanation: Load torques can have two types. They are active and passive load torques. Active load torques are able to run the motor under equilibrium conditions and their sign remains the same even if the motor rotation changes but passive load torques always opposes the motion by changing their sign with the change in rotation of the motor.
