A body is pivoted at some point. How much force is required to produce 40 N m torque, when it is applied at a distance of 200 cm from the pivot?
Given, the moment of force = 40 N m
Distance from the pivot, r = 200 cm = 2 m
Let the force applied be F
Then ,the moment of force = force × distance from the pivot
or, 40 N m=F×2 m
or, F=40 N m2 m=20 N
