One end of a light uniform rod is attached to a wall by a frictionless hinge. The rod is held in a horizontal position by a wire that runs from the other end of the rod to the wall. The wire has length 3.00m and makes an angle of 30.0 with the rod. A block with mass m is suspended by a light rope attached to the middle of the rod. The transverse fundamental standing wave on the wire has frequency f . The mass m is varied and for each value the frequency is measured. You plot f2 versus m and find that your data lie close to a straight line with slope 19.4 kg1s2
