I tot = I rod abot the axis+Idisk alout the center+I*d^2
d = R+R = 2R
I rod abot the axis = 1/3*3MR^2 = MR^2
Idisk alout the center = 1/2*2MR^2 = MR^2
Itot = MR^2+MR^2+2M(R+R)^2
Itot = 2MR^2+8MR^2
Itot = 10MR^2

A grandfather clock has a pendulum that consists of a thin brass disk of radius r = 14.38 cm and mass 0.8261 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, as shown in the figure. If the pendulum is to have a period of 1.592 s for small oscillations at a place where g =...
6. A rigid sculpture consists of a thin hoop of mass m and radius R and two thin rods each of mass m and length L = 2R. The sculpture can pivot around a horizontal axis in the plane of the hoop passing through its center. What is the sculpture's rotational inertia I about the rotation axis in terms of m and R. rotation axis Answer | 1 = 58mR2

A grandfather clock has a pendulum that consists of a thin brass
disk of radius 37 cm and mass 1.6 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 grandfather clock has a pendulum that consists of a thin brass
disk of radius 27 cm and mass 1.1 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

An object is formed by attaching a uniform, thin rod with a mass of mr = 7.31 kg and length L = 5.68 m to a uniform sphere with mass ms = 36.55 kg and radius R = 1.42 m. Note ms = 5mr and L = 4R. *What is the moment of inertia of the object about an axis at the left end of the rod? *If the object is fixed at the left end of the rod, what...
2. Naruto's whack-a-smacker ninja-tool consists of a 3.42 kg copper ball of 9 cm diameter and a 4.1 kg steel ball of 10 cm diameter, rigidly joined by a 1.0 kg steel rod, 30 cm long. (a) Find the moment of inertia of this tool with respect to an axis that is perpendicular to the connecting rod and passes through its centre. Ignore the fact that the rod has finite diameter (here: 1.3 cm) and treat it as infinitely thin...
A grandfather clock has a pendulum that consists of a thin brass disk of radius 40 cm and mass 1.9 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...
