Question

How do clockwise and counterclockwise torques compare when a system is balanced?

Answer 1

Explained

Step-by-step explanation:

For a system to be balanced the magnitudes of the clockwise and counterclockwise torque has to be same. Also, their direction need to be opposite to each other.

consider a plank AB of 10 m long pivoted a distance of 5 m from point A and two equal force of 10 N act downward in these points A and B.

torque at A(left side) = 10*5 =50 N-m (counter clockwise)

Torque at B ( right ward) = 10*5= 50 N-m (clockwise)

now since torque are equal and opposite they will cancel each other.
