Question

A 5 N.m torque is required to open a bolt. Calculate the amount of force to be applied on the spanner at a length of 25 cm from the bolt.

Answer 1

Given Date:

Torque (τ) = 5 N.m

Length of the spanner (r) = 25 cm = `25/100` m = 0.25 m

Formula:

Torque (τ) = Force (F) × Distance (r)

5 = F × 0.25

F = `5/0.25`

F = 20 N

The amount of force to be applied is 20 N.
