Problem 9Q
Can the sum of the torques on an object be zero while the net force on the object is nonzero? Explain.
Solution
Is it possible for an object to have zero net torque but non zero net force.
If the net torque is zero, the object is in rotational equilibrium.
If the net force is zero, the object is in translational equilibrium.
All objects which are rotationally in equilibrium but translational not, has zero net torque but non zero net force.
An object making accelerated motion without rotating has non zero net force, but zero net torque on it.
The rod above with two forces on two ends has zero net torque about the center of the rod but non zero net force.
