Question

When tightening a bolt, you push perpendicularly on a wrench with a force of 185 N at a distance of 0.11 m from the center of the bolt. How much torque are you exerting relative to the center of the bolt

Answer 1

Explanation:

The torque exerted on the wrench is

$\tau = Fd\sin{\theta} = Fd$

since the force is applied perpendicular to the wrench, in which sin90 = 1. The torque then is

$\tau = (185\:\text{N})(0.11\:\text{m}) = 20.35\:\text{N-m}$
