A thin, light wire is wrapped around the rim of a wheel, as shown in the following figure. The wheel rotates without friction about a stationary horizontal axis that passes through the center of the wheel. The wheel is a uniform disk with radius 0.266 m. An object of mass 4.15 kg is suspended from the free end of the wire. The system is released from rest and the suspended object descends with constant acceleration.

A uniform rod of length L and mass M is held vertically with one end resting on the floor as shown below. When the rod is released, it rotates around its lower end until it hits the floor. Assuming the lower end of the rod does not slip, what is the linear velocity of the upper end when is hits the floor?
Let’s approximate the motion of a yo-yo with that of a solid cylinder with a string wrapped around it. The string has alength of 1.2 m and the cylinder has a mass of 0.1 kg and a radius of 0.05 m. Suppose the cylinder was released atrest from the top, what would be its velocity when it reaches the bottom?
A person holds his outstretched arm at rest in a horizontal position. The mass of the arm is m and its length is 0.740 m.When the person releases his arm, allowing it to drop freely, it begins to rotate about the shoulder joint. Find (a) theinitial angular acceleration of the arm, and (b) the initial linear acceleration of the man’s hand. (Hint: In calculatingthe torque, assume the mass of the arm is concentrated at its midpoint. In calculating the angular acceleration, use themoment of inertia of a uniform rod of length L about one end; I = 13mL2.)
A 255-lbf block is suspended from an inextensible cable which is wrapped around a drum of 1.75-ft radius rigidly attached to a flywheel. The drum and flywheel have a combined centroidal moment of inertiaI̅= 12 lb . ft . s 2 . At the instant shown, the velocity of the block is unknown directed downward. Knowing that the bearing at A is poorly lubricated and that the bearing friction is equivalent to a couple M of magnitude 65 lb .ft, determine the velocity of the block before it has moved 3.5 ft downward if at S2 speed is 13.5ft/s. (The final answer should be in two decimal places with correct units)

Consider that instead of the force F, a block with mass m = 0.32 kg (with force F = 3.139 N) and radius R = 13.0cm is attached to the cylinder with a massless string (see Figure). The cylinder is changed to one with the same mass and radius, but a different moment of inertia. Starting from rest, the mass now moves a distance 0.5647 m in a time interval of 0.57 s. Find Icm of the new cylinder.
A cylinder of mass M and radius R is pulled by a constant force of magnitude Fapplied at the top horizontally. The cylinder rolls smoothly on the horizontal surface.

A solid cylinder of radius 0.300 [m] is wrapped with a massless string. Holding the free end of the string stationary, the cylinder is dropped from a heightof 2.00 [m] from the ground. Right before it hits the ground, the cylinder was found to have an angular velocity of 3.00 [rad/s]. Assuming that the string does not slip or stretch as the cylinder descends and rotates, what is the angular acceleration of the cylinder?

A uniform, solid cylinder of mass mc=6.35 kg and radius R=0.31 m is attached at its axle to a string. The string is wrapped around a small "ideal" pulley (negligible friction, Icm≈0) and is attached to a hanging block of mass mb=3.65 kg as indicated in the above figure. You release the objects from rest and the cylinder rolls without slipping. What is the magnitude of the acceleration of the block?
