Problem 12.9 A solid sphere is cut in half and a homogeneous hemi- sphere of radius r and mass M is set upon a table (with its flat side up). The surface of the table is perfectly rough. The hemisphere rocks land forth with small amplitude excursions from equilibrium. What he length of an equivalent simple pendulum? Justify approximations. te that the center of mass of a hemisphere is at a distance 3r/8 below the center of the sphere.
RO O A crucial part of a piece of machinery starts as a flat uniform cylindrical disk of radius Ro = 0.46 m and mass M = 22.68 kg. It then has a circular hole of radius R1 = 0.08 m drilled into it. The hole's center is a distance h = 0.08 m from the center of the disk. Find the moment of inertia of this disk (with off-center hole) when rotated about its center, in kg m².
A crucial part of a piece of machinery starts as a flat uniform
cylindrical disk of radius R0 and mass M. It then
has a circular hole of radius R1 drilled into it, see the
figure.(Figure 1) The hole's center is a distance h from
the center of the disk.
1. Find the moment of inertia of this disk (with off-center
hole) when rotated about its center, C. [Hint: Consider a
solid disk and "subtract" the hole; use the parallel-axis...
A very thin circular hoop of mass(m) and radius(r) rolls without slipping down a ramp inclined at an angle(theta) with the horizontal, as shown in the figure.What is the acceleration(a) of the center of the hoop? Express your answer in terms of some or all of the variablesm,r, theta, and the magnitude of the acceleration due to gravity(g).
A cylinder of mass M and radius R is rolling down an incline with angle theta. Find the acceleration of the cylinder as it rolls down the incline. Find the acceleration a and the tension T in the string of a yo-yo when it is released.

Question 1 0/1 pts Aladder leans against a wall, an angle theta from the horizontal direction. (that is, theta =0 would mean horizontal). The ladder has mass M, and a person of mass m stands at the center of the ladder. What is the minimum necessary coefficient of static friction mu_s with the ground, such that the ladder will not slip out? sin(theta) / (2 cos(theta)) cos(theta)/(2 sin(theta)) Msin(theta)/(2(M+m) cos(theta)) Mcos(theta)/(2(M+m) sin(theta)) 0 1 1 nts

Q7. For 2 points, in the space to the right, sketch a 3 kg thin flat, homogeneous, plate of radius 160 mm and uniform thickness, except in the concentric central portion of radius 80 mm, where the thickness is doubled. Find the flat surface areas of the a) Larger circle b) Smaller circle and determine the moment of inertia of the system about its center of mass.
The box is at a ramp tilted an angle theta degrees from the horizontal. Assume that the mass of the box is 500kg and the coefficient of static friction between the box and the ramp is \mu_k=0.3. Calculate the angle theta where the box starts moving. Will the box tip or slide? 2m, 1.5m
