A rod (0.05 m) is attached to an axle (length 2 m, circular cross section of radius 0.01 m) so that it makes a right angle (see figure). A force is applied to the free end of the rod which is perpendicular to both the rod and the axle, so the rod exerts a torque τ1 = 4 Nm about the axis of the axle where the rod connects to the axle. The other end of the axle is connected to a plate. Nothing is moving.
At the end of the axle which is connected to a plate, there is a torque τ2 exerted by the axle on the plate. How does the torque τ2 compare with τ1?
