A person is trying to tighten a bolt of mass 1 kg using a wrench of mass 6 kg and length

15 cm by applying a force of 12 N as shown in the diagram below. What is the torque

applied?

0.18 Nm

Explanation:

Note: Torque is independent of the mass of a body.

From the question,

T = F*d ... Equation 1

Where T = Torque, F = force applied to the wrench, d = length of the wrench.

Given: F = 12 N, d = 15 cm = 0.015 m

Substitute into equation 1

T = 12 (0.015)

T = 0.18 Nm.

Hence the torque applied is 0.18 Nm
