Question

A person exerts a force of 50 N on the end of a door 71 cm wide. (a)What is the magnitude of the torque if the force is exerted perpendicular to the door? (b) What is the magnitude of the torque if the force is exerted at a 45 degree angle to the face of the door?

Explanation / Answer

given force f = 50 N

d = 0.71 m

a) torque = d*f sin90

torque = 0.71*50 = 35.5 N m

b) torque = dfsin45 = 0.71*50sin45 = 25.1 Nm
