Questions & Step-by-Step Solutions

What is the condition for an object to be in rotational equilibrium?
  • Step 1: Understand what rotational equilibrium means. It means that an object is not rotating or is rotating at a constant speed.
  • Step 2: Know that torque is a force that causes an object to rotate around an axis.
  • Step 3: Realize that for an object to be in rotational equilibrium, all the torques acting on it must balance each other out.
  • Step 4: This means that the total (net) torque acting on the object must be zero.
