3. In the figure above, a spool or pulley with moment of inertia MR2 is hanging from a ceiling by a (massless, unstretchable) string that is wrapped around it at a radius R, while a block of equal mass M is hung on a second string that is wrapped around it at a radius r as shown. Find the magnitude of the acceleration of the the central pulley.

One simple way to measure the moment of inertia of an irregular object is shown in the diagram. The object is mounted on a frictionless axis. A light string is wrapped around the object, passes over a light pulley (so it has negligible moment of inertia itself), and then connected to mass M = 40.6 kg. The system is released from rest. After mass M has fallen distance 4.05 m it is moving 2.67 m/s and the object has reached...

1. A pulley (radius = 0.20 m) is mounted on a frictionless, horizontal axis. A nearly massless string is wrapped around the pulley and supports a hanging mass of 0.55kg. When released from rest the mass falls with a downward acceleration of 5.1 m/s. What is the moment of inertia of the pulley? (8pts) el (@9

A string is wrapped around a pulley of mass m, radius r and unknown moment of interia. The pulley can rotate freely about its axis without friction. The loose end of the string is attached to a block of mass m. If the magnitude of the angular acceleration of the pulley is 7g/12r what is the moment of interia of the pulley?

The pulley shown (Figure 1) has a moment of inertia IA = 0.625
kg⋅m2 , a radius r = 0.250 m , and a mass of 20.0 kg. A cylinder is
attached to a cord that is wrapped around the pulley. Neglecting
bearing friction and the cord’s mass, express the pulley’s final
angular velocity in terms of the magnitude of the cord’s tension, T
(measured in N), 4.00 s after the system is released from rest. Use
the principle of...

5. Consider the system illustrated in the figure. The pulley with radius R and moment of inertia I around its fixed axis is mounted on a frictionless axle which is fixed to the table. Th has one end fixed to the table, and the other end is attached to a massless inextensible rope. Th and a mass m hangs at its other end. Initially, the system is at rest e spring with stiffness constant k e rope passes over the...

3. An experiment is set up as shown in Figure Q3 to measure the moment of inertia of a circular flywheel. The mass of 30 kg is attached to a light inextensible string which is wrapped around the outer diameter of the flywheel which has a radius of 0.4 m. The mass is released when the system is at rest and drops 5.4 m in a time of 3 seconds. Friction in the bearings can be neglected Flywheel Bearing 30...

SECTION 3 - Newtonian Dynamics 3 (a) A rope (that can be considered massless) is wrapped around a horizontal cylinder of mass M and radius R. The cylinder is free to rotate, and a mass m is hanging on the end of the rope as shown in the diagram. When the mass is released, it falls under the effect of gravity. Show that the downward acceleration a of the hanging mass is: 1 + M/2m...

3) A horizontal circular platform can rotate around a vertical axis at its center with negligible friction. You decide to use the rotating platform to design a procedure that will allow you to determine the unknown rotational inertias of different objects, for example a bowl. You know the rotational inertia of the platform Ip. Which of the following procedures would serve your task? Comment on why. (More than one answer could be correct). Comment on the procedures that are not...
