## anonymous 3 years ago When tightening cylinder-head bolts in a car, the crucial quantity is the torque applied to the bolts. why is this more important than the actual force applied to the wrench handle? pls help. tnx

1. anonymous

The motion of bodies which rotate around an axis is governed by torque versus mass. The long handle of the wrench INCREASES the force appled at the end by the leverage principle

2. anonymous

Torque ON the bolt is$\it F_{on-bolt}\times Radius_{bolt} = Torque$

3. anonymous

So the actual FORCE-ON-BOLT is crucial
