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.)

The 1.5-m-long brass pendulum of a grandfather clock was manufactured on a day when the temperature was 27°C. The coefficient of linear expansion for brass is 19 ? 10?6/°C. (a) What would the length be if the temperature were to increase to 31.0°C?

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.

A thin uniform rod has a length of 0.490 m and is rotating in a circle on a frictionless table. The axis of rotation is perpendicular to the length of the rod at one end and is stationary. The rod has an angular velocity of 0.37 rad/s and a moment of inertia about the axis of 3.50×10−3 kg⋅m2 . A bug initially standing on the rod at the axis of rotation decides to crawl out to the other end of...

A 0.810 m long brass pendulum experiences a 19.0°C temperature increase. (a)Calculate the original period (in s). (b) What is the change (in s) in the period? (c) Find the ratio (in h) of the change in period to the original period, and calculate how long a clock run by this pendulum would take to fall 1.00 s behind the correct time.

A thin, rigid, uniform rod has a mass of 1.40 kg and a length of 2.50 m. (a) Find the moment of inertia of the rod relative to an axis that is perpendicular to the rod at one end. (b) Suppose all the mass of the rod were located at a single point. Determine the perpendicular distance of this point from the axis in part (a), such that this point particle has the same moment of inertia as the rod...
