When tightening a bolt, you push perpendicularly on a wrench with a force of 165 N at a distance of 0.140 m from the center of the bolt. How much torque are you exerting in Nm (relative to the center of the bolt)?

To calculate the torque exerted, you need to multiply the force by the distance from the center of the bolt at which the force is applied.

Torque (τ) = Force (F) x Distance (r)

Torque = 165 N x 0.140 m
Torque = 23.1 Nm

Therefore, you are exerting a torque of 23.1 Nm relative to the center of the bolt.
