The Minimum Force Required Using a Wrench
The lug nuts on a car wheel require tightening to a torque of 90 n ∙ m. If a 30-cm long wrench is used, what is the magnitude of the minimum force required using the wrench? Torque = τ = 90 Nm r = length of the wrench = 30 cm = 0.30 m F = force Torque is given as τ = F r F = 90/0.3 = 300 N Therefore, the magnitude of the minimum force required using the wrench is 300 N.The lug nuts on a car wheel require tightening to a torque of 90 n ∙ m.
