Question

Suppose the torque produced by a wrench on a stubborn nut is 30 Nm. If the lever arm is doubled with no changein force, what is the resulting torque?

Answer 1

Given data

*The torque produced by a wrench on a stubborn is 30 N.m

The formula for the torque is given as

$T\text{=F.r}$

*Here F is the perpendicular force

*Here r is the distance

Now, if the lever arm is doubled with no change in force, then the resulting torque is also gets doubled

$T=60\text{ N.m}$
