1. A force of 60 Newtons is applied to the end of a wrench 0.12 m long. How much torque is produced?

7.2 N. m.

Explanation:

Torque is defined as the force and the distance in which it is acting.

Mathematically,

τ = d * F sin θ

Given:

Force = 60N

d = 0.12m

The force is applied at the end of the wrench, therefore it is applied at 90°.

τ = rF sin θ

= 0.12*60*sin90

= 0.12 * 60

= 7.2 N. m.

Torque is given as = r * F

Then,

τ = rF sin θ

Force (F) = 60N

r=0.12m

Then,

τ = rF sin θ

If it is applied at the end of the wrench it is applied at 90°

Then,

τ = rF sin θ

τ = 0.12*60*sin90

τ = 7.2Nm
