A screwdriver is used to loosen a screw nail. The radius of the handler is 4.0 cm. The nail puts the force at 0.2 cm from the axis. The picture is shown. You apply 10 N force to loosen the nail. How much force does the nail apply to the screwdriver?

200 N

Explanation:

Torque at handle = torque at nail

τ = τ

Fr = Fr

(10 N) (4.0 cm) = F (0.2 cm)

F = 200 N
