Transcribed Image Text:A grandfather clock uses a pendulum to measure time. A model of this pendulum is constructed as follows: One
end of a rod of length l = 1.0 m and mass m,od = 0.65 kg is connected to a bearing (assume friction-less) and the
other end connects to a solid cylinder of radius R = 0.12 m. You wish to find the mass of the cylinder such that the
period of oscillation is T = 2 s.
1. Find the moment of inertia of the rod and disk.
2. Calculate the distance between the pivot and the center of mass of the pendulum.
3. Calculate the mass of the cylinder such that the period of oscillation is T = 2s.
4. Write down the equation of motion of the cylinder 0(t), assuming the angle of release is small sin(0) = 0).
5. Determine the velocity of the pendulum bob after swinging for 0.73 s, if the pendulum is released from a
maximum release angle of 0 = 0.1 rad at time t = 0.

- In the experiment, you will study an oscillator called a "torsion pendulum." In this case, the restoring "force" is the torsion constant of the wire that suspends the weight X and the inertial term is the rotational inertia of the suspended mass. You will compare the periods of a suspended sphere and of a suspended cube. The rotational inertia of a sphere is Is = 1/10msD^2, where ms is the mass of the sphere and D is its diameter. The rotational inertia of a cube is Ic = 1/6mcS^2, where mc is the mass of the cube and S is the length of its side. If the cube and the sphere are suspended from the same wire, what is the expected ratio of their periods, Tc/Ts? Assume that D = S, ms = 0.20kg, and mc = 0.5 kg.arrow_forwardA peg on a turntable moves with a constant tangential speed of 0.67 m/s in a circle of radius 0.26m. The peg casts a shadow on a wall.
