A uniform metal rod of mass 100 kg and length L (=2.5 meters) is suspended from the side of a building as shown in the figure. On the far end a mass of 100 kg is hung by a rope, (distance L from the building). The rod is connected to the building on the left end by a pivot, (and a force F is extend on the rod by the pivot). To hold thips up a strong cable is attached a distance L/4 from the pivot (and has a tension T on it).
a)The system is in equilibrium.
Using rotational equilibrium and torque, find the tension in the cable.
b) Using net forces, calculate the force the pivot exerts on the rod.
