Question

A mechanic uses a 12 -in. wrench to turn a bolt. The wrench makes a $30^{\circ}$ angle with the horizontal. If the mechanic applies a vertical force of 10 lb on the wrench handle, what is the magnitude of the torque at point P (see the following figure)? Express the answer in foot-pounds rounded to two decimal places.
