When tightening a bolt, you push perpendicularly on a wrench with a force of 167 n at a distance of 0.1450 mm from the centre of the bolt. a) how much torque are you exerting (relative to the centre of the bolt)

0.0242 Nm

Explanation: The distance of 0.145 mm is very small. This will also result in a small ttorque. The question would make more sense if the distance was 0.145 m. Answering with the 0.145 mm as distance :

Changin from mm to m : 1mm=0.001m

0.145 mm = 0.000145 m

The formula for Torque is T=Fxd

Wher F is the force and d is the perpendicular distance between the centre of the bolt and the applied force.

T= 167 x 0.000145 = 0.024215 Nm
