A 1.6-kg tube AB can slide freely on rod DE which in turn can rotate freely in a horizontal plane. Initially the assembly is rotating with an angular velocity of magnitude w = 5 rad/s and the tube is held in position by a cord. The moment of inertia of the rod and bracket about the vertical axis of rotation is 0.30 kg.m2 and the centroidal moment of inertia of the tube about a vertical axis is 0.0025 kg.m2If the cord suddenly breaks, determine (a) the angular velocity of the assembly after the tube has moved to end E, (b) the energy lost during the plastic impact at E.

A shaft with 3 meters span between two bearings carries two masses of 10 kg and 20 kg acting at the extremities of the arms 0.45 m and 0.6 m long respectively. The planes in which these masses rotate are 1.2 m and 2.4 m respectively from the left end bearing supporting the shaft. The angle between the arms is 60°. The speed of rotation of the shaft is 200 r.p.m. If the masses are balanced by two counter-masses rotating with the shaft acting at radii of 0.3 m and placed at 0.3 m from each bearing centers, estimate the magnitude of the two balance masses and their orientation with respect to the X-axis, i.e. mass of 10 kg ‎‏Note: It must be solved using the graphic method, not the equations method.
A double radius pulley is attached to a wall by an axle of negligible friction and is initially at rest. Two vertical forces,both with magnitude F1P = F2P =19 N, are applied at the radii R1 =0.4 m and R2 =1 m as shown.Determine the kinetic energy of the pulley after it has undergone one full rotation.
In the figure, the hanging object has a mass of m1 = 0.420 kg; the sliding block has a mass of m2 = 0.850 kg, and the pulley is a hollow cylinder with a mass M = 0.350 kg, a interior radius R1 = 0.0200 m and an exterior radius R2 = 0.0300 m. Assume that the mass of the rays is negligible. The coefficient of kinetic friction between the block and the surface horizontal is µk = 0.250. The pulley rotates without friction on its axis. The lightweight cable does not stretch and does not slip on pulley. The block has a velocity of vi = 0.820 m / s towards the pulley when you pass a landmark on the table. (a) Use energetic methods to predict its velocity after it has passed a second point, which is at 0.700 m. (b) Find the angular speed of the pulley at the same moment.

A flywheel is a mechanical device used to store rotational kinetic energy for later use. Consider a flywheel in the form of a uniform solid cylinder rotating around its axis, with moment of inertia I = 1/2 mr2. 1) Consider a scenario in which the flywheel described in part (a) (r1 = 0.55 m, mass m1 = 16 kg, v = 45 m/s at the rim) is spinning freely at its maximum speed, when a second flywheel of radius r2 = 2.8 m and mass m2 = 11 kg is coaxially dropped from rest onto it and sticks to it, so that they then rotate together as a single body. Calculate the energy, in joules, that is now stored in the wheel. 2) Return now to the flywheel of part (a), with mass m1, radius r1, and speed v at its rim. Imagine the flywheel delivers one third of its stored kinetic energy to car, initially at rest, leaving it with a speed vcar. Enter an expression for the mass of the car, in terms of the quantities defined here.
