The second condition of equilibrium in a parallel force is a

The second condition of equilibrium in a parallel force is a clockwise and counterclockwise torques are unequal. b. clockwise and counterclockwise torques are equal. c. there are no torques.

Solution

The sum of moments tending to rotate the body clockwise about a point must equal the sum of moments tending to rotate the body counterclockwise about the same point: M = 0.

This translates to clockwise and counterclockwise torques are equal.

This is the second condition

Hence the answer is b.

PS: The first condition is that the sum of the forces pulling the body in one direction must equal the sum of the forces pulling the body in the opposite direction: F = 0
