Question

Find
the
resultant torque.​

Answer 1

Answer: 110 N-m into the plane of paper.

Explanation: As you may have studied that

Torque = Force * Perpendicular distance from axis

Now the torque due to 30N & 50N force are in same direction ( right hand rule ) and so is torque due to 80N and 20N force .and torque 200 Newton force is equal to zero as it lies in the line passing through the axis of the body around which the torque is to be calculated so,

Net torque = [{ ( 50 * 5) + ( 30 * 4 )} - {( 80 * 3) + ( 20 * 1 )}]

= 110 N-m
