The wire has length 2.00 m and makes an angle of 30.0° with the rod. A block with mass m is sus- pended 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 20.4 kg-1.s-2. What is the mass of the wire? Assume that the change in the length of the wire when the tension changes is small enough to neglect.

an irregularly shaped plastic plate withuniform thickness and density (mass per unit volume) is to berotated around an axle that is perpendicular to the plate faceand through point O. The rotational inertia of the plate about that axle is measured with the followingmethod. A circular disk of mass 0.500 kg andradius 2.00 cm is glued to the plate, with itscenter aligned with point O . Astring is wrapped around the edge of the diskthe way a string is wrapped around a top.Then the string is pulled for 5.00 s. As a result,the disk and plate are rotated by a constantforce of 0.400 N that is applied by thestring tangentially to the edge of the disk.The resulting angular speed is 114 rad/s.What is the rotational inertia of the plateabout the axle?
The left-hand end of a uniform rod of mass 2.00 kgkg and length 1.10 mm is attached to a vertical wall by a frictionless hinge. The rod is held in a horizontal position by an aluminum wire that runs between the right-hand end of the rod and a point on the wall that is above the hinge. The cross-sectional radius of the wire is 2.50 mmmm, and the wire makes an angle of 30.0∘∘ with the rod. What is the length of the wire? Express your answer with the appropriate units. An object of mass 90.0 kgkg is suspended from the right-hand end of the rod. What is the increase in the length of the wire when this object is added? Express your answer with the appropriate units. In your analysis do you need to be concerned that the lengthening of the wire means that the rod is no longer horizontal?
