4. Christy has a grandfather clock with a pendulum that is 3.160 m long. Christy observes the actual period of the clock, and finds that it is 1.00% faster than that for a simple pendulum that is 3.160 m long. If Christy models the pendulum as two objects, a 3.160-m uniform thin rod and a point mass located 3.160 m from the axis of rotation, what percentage of the total mass of the pendulum is in the uniform thin rod?

A grandfather clock has a pendulum that consists of a thin brass disk of radius 21 cm and mass 1 kg that is attached to a long, thin rod of negligible mass. The pendulum swings freely about an axis perpendicular to the rod and through the end of the rod opposite the disk. The pendulum should be designed so that its period is 2 s for small oscillations when the gravitational acceleration is 9.8 m/s2. (a) What should the length...

Question intro: A trade’s person is constructing a very large, old-fashioned grandfather clock by hand. The pendulum arm of this clock consists of a uniform rod (mass m and length L) with a uniform disk (mass m and radius r=L/4) at one end. The other end of the pendulum is fixed to a frictionless, horizontal axis such that the pendulum arm can rotate in a vertical plane Question 1: What is the symbolic expression for the gravitational potential energy of...

The pendulum of a clock consists of a mass of 0.20 kg hanging from a thin rod. The amplitude of the pendulum swing is 3.0 cm. The clock is driven by a weight of mass 4.5 kg that falls a distance of 0.95 m over a period of 8 days. Assuming the pendulum to be a simple pendulum of length 0.75 m, show that the Q-value of the clock is approximately 70. (Assume g = 9.81 m s−2.)

A long, thin rod of length l and mass m hangs from a pivot point about which it is free to swing in a vertical plane like a simple pendulum. Calculate the total angular momentum of the rod about the pivot point as a function of its instantaneous angular frequency ω. Calculate the total kinetic energy of the rod.
