The picture below shows a model of a human leg with a heavy weight on the ankle. It represents a person lying on his back doing leg-lifts to exercise the quadriceps. In the model, the stick (c.g. in the middle) has a length of 1.24 m and a mass of 7.50 kg, while the added mass of 2.60 kg is located 24 cm from the right (non-pivot) end of the stick. The stick makes a 55° angle with the horizontal. The stick is supported by a hinge at the left end (pivot) and a rope attached 16 cm from the left end making a 12° angle with the stick.

a) What is the magnitude of the gravitational torque (in N·m) due to the weight of the stick?
