A turntable is used to test an intentionally weak adhesive by coating the bottom of a 0.3 kg block with the adhesive and pressing it firmly to the turntable 0.4 meters from its center. The turntable starts from rest at t=0 and uniformly accelerates with an angular acceleration of a= 4.5 rad/s^2. If the adhesive fails exactly 2 seconds after the turntable starts rotating determine: (a) The angular displacement of the turntable at the time of failure. (b) The number of revolutions the turntable has made at the time of failure. (c) The total shear force which the adhesive supports given this failure.

A Texas cockroach walks from the center of a circular disk (that rotates like a merry-go-round without external torques) out to the edge at radius R. The angular speed of the cockroach–disk system for the walk is (va = 5.0 rad/s and vb = 6.0 rad/s). After reaching R, what fraction of the rotational inertia of the disk does the cockroach have?
A machine part has the shape of a solid uniform sphere of mass 255 g and diameter 4.50 cm . It is spinning about a frictionless axle through its center, but at one point on its equator it is scraping against metal, resulting in a friction force of 0.0200 N at that point. Find its angular acceleration. Let the direction the sphere is spinning be the positive sense of rotation. How long will it take to decrease its rotational speed by 20.0 rad/s ?
A wheel of radius 0.35 m rotates in a clockwise sense about a fixed axle with negligible friction at an initial angular speed of 2.6 rad/s. The wheel's mass of 17 kg is concentrated in its rim.
