Question
Which of the following is/are true of a rotational equilibrium? (a) A body at a rotational equilibrium may be at rest or may be rotating at a constant angular speed; (b) Clockwise torque is equal to counter-clockwise torque but opposite in direction; (c) Net torque on the system is zero; (d) All of the above are true of a body at a rotational equilibrium......... Which of the following is/are true of a rotational equilibrium? (a) A body at a rotational equilibrium may be at rest or may be rotating at a constant angular speed; (b) Clockwise torque is equal to counter-clockwise torque but opposite in direction; (c) Net torque on the system is zero; (d) All of the above are true of a body at a rotational equilibrium.........Explanation / Answer
d) all of the above.
Net torque should be zero.
It means closkwise torque should be equal to counter-clockwise torque.
or, the body should be at rest.
