1.

You are asked to find the force.

2.

You are given the force and lever arm for one condition.

3.

Use: = r F.

4.

Solve for the torque required to loosen the bolt

= (50 N)(0.2 m) = 10 Nm

Calculate the torque with a force applied at 30 degrees:

10 Nm = F × (0.2 m) cos 30o = 0.173 F

F = 10 Nm ÷ 0.173 = 58 N.   It takes a larger force at 30o.

Calculating a torque from an angled force

A 20-centimeter wrench is used to loosen a bolt.

The force is applied 0.20 m from the bolt.

It takes 50 newtons to loosen the bolt when the force is applied perpendicular to the wrench.

How much force would it take if the force was applied at a 30-degree angle from perpendicular?
