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.

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
