A uniform rod has one end attached to a vertical wall by africtionless hinge. A horizontal wire runs from the other end of the rodto a point on the wall above the hinge and holds the rod at an angle θabove the horizontal. You vary the angle u by changing the length ofthe wire, and for each θ you measure the tension T in the wire. You plotyour data in the form of a T-versus-cot u graph. The data lie close to astraight line that has slope 30.0 N. What is the mass of the rod?

Question
A uniform rod has one end attached to a vertical wall by a
frictionless hinge. A horizontal wire runs from the other end of the rod
to a point on the wall above the hinge and holds the rod at an angle θ
above the horizontal. You vary the angle u by changing the length of
the wire, and for each θ you measure the tension T in the wire. You plot
your data in the form of a T-versus-cot u graph. The data lie close to a
straight line that has slope 30.0 N. What is the mass of the rod?
