Answer:
Explained
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.
