derive an expression for the 59. ** angular acceleration of the pulley of moment of inertia I in Figure 8-62. Assume the friction between the pulley and its axle are negligible. Also assume that the friction between the masses and the surfaces is negligible. m2 Either Conservation of energy or Newton's Second Law. mi Since a is being asked for, (and not w) perhaps easier to use Newton's 2nd law approach.
Two blocks are connected by a lightweight string passing over a pulley, as shown in the figure below. The block with mass m1 = 16.5 kg on the incline plane accelerates up the plane with negligible friction. The block's acceleration is a = 1.40 m/s2, and the tension in the segment of string attached to this block is T1. The hanging block has a mass of m2 = 23.5 kg, and the tension in the string attached to it is T2....
In the pulley system shown in Figure P2.33, assume that the cable is massless and inextensible, and assume that the pulley masses are negligible. The force f is a known function of time. Derive the system's equation of motion in terms of the displacement. For the system shown in Figure P2.34, the solid cylinder of inertia I and mass m rolls without slipping. Neglect the pulley mass and obtain the equation of motion in terms of x.

As shown in the figure below, two blocks are connected by a string of negligible mass passing over a pulley of radius 0.270 m and moment of inertia I. The block on the frictionless incline is moving with a constant acceleration of magnitude a = 1.20 m/s2. (Let m1 = 15.5 kg, m2 = 22.0 kg, and θ = 37.0°.) From this information, we wish to find the moment of inertia of the pulley. (a) What analysis model is appropriate...

Q3-(25 pts) A pulley of mass Mand radius R can rotate around its center of mass freely. Take the moment of inertia of the pulley as 1o. A string with negligible mass is wrapped around the pulley. One end of the string holds a block with mass m and the other end is attached to a spring with a force constant k. Assume no friction at any surface and string is not slipping on pulley. a) When the system is...
