Question

A nut has been tightened by a force of 200n using 10cm longer spanner what spanner is required to loosen the the same nut with 150n force

Answer 1

Answer:

Let the length needed is x

Torque = R Cross(Cross Product) F

Initial Torque = 200*0.1 = 20 nm

Torque needed

20 = 150*x

x = 0.13 m

Explanation:

The Torque needed to lose the nut will be the same
