Answer:
Torque is defined as the force that produces rotation around the axis of an object. Torque is also known as the moment of force. It's S.I unit is Nm.
Formula of torque is:
τ= rxF(sinθ)
Given Data:
Force = 20 N
r = 0.25 m
θ = 120°
Solution:
τ= rxF(sinθ)
= 0.25 x 20 (sin 120)
= 2.903 Nm
Thus, the total torque applied on the wrench is 2.903 Nm.
