Fixed torque is applied to a body. What will be generated in the body?
- a.Angular acceleration
- b.Linear acceleration
- c.Angular velocity
- d.Angular displacement
Answer: (A) Angular acceleration
The rotational form of Newton's second law is $\tau = I\alpha$, so a constant torque produces a constant angular acceleration. Angular velocity and displacement then change over time as a result, and linear acceleration needs a net force rather than a torque.
