Question

When you apply the torque equation \(\sum {\tau = 0} \) to an object in equilibrium, the axis about which the torques are calculated

(a) must be located at a pivot.

(b) must be located at the object’s center of gravity.

(c) should be located at the edge of the object.

(d) can be located anywhere.

Short answer

The correct option is (d).

Step-by-step solution

Concepts

At equilibrium, the net torque is zero. The torque is zero about any point on an object when the object is in equilibrium.

Explanation

When an object is at equilibrium, it is not rotating. Therefore, the torque about any axis through the object is zero.

Hence, option (d) is correct.
