- In the figure, what magnitude of force applied horizontally at the axle of the wheel is necessary to raise the wheel over an obstacle of height h = 0.315 m? The wheel's radius is r = 0.642 m and its mass is m = 1.45 kg. Number Units Use correct number of significant digits; the tolerance is +/-2%An m 10.8kg mass is attached to a cord that is wrapped around a wheel of radius r= 11.9cm (see the figure below). The acceleration of the mass down the frictionless incline is measured to be a = 2.17m/s^2. Assuming the axle of the wheel to be frictionless, and the angle to be 8 = 36.5deg determine the tension in the rope.

- A hanging weight, with a mass of m, = 0.370 kg, is attached by a cord to a block with mass m, = 0.860 kg as shown in the figure below. The cord goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R, = 0.0200 m, and an outer radius of R, = 0.0300 m; the mass of the spokes is negligible. As the weight falls, the block slides on the table, and the coefficient of kinetic friction between the block and the table is Hy = 0.250. At the instant shown, the block is moving with a velocity of v, = 0.820 m/s toward the pulley. Assume that the pulley is free to spin without friction, that the cord does not stretch and does not slip on the pulley, and that the mass of the cord is negligible. R2 R (a) Using energy methods, find the speed of the block (in m/s) after it has moved a distance of 0.700 m away from the initial position shown. m/s (b) What is the angular speed of the pulley (in rad/s) after the block has moved this distance?…A winch with a drum of radius ?� pulls a block at constant speed up a rough incline.

The fixed, wedge-shaped ramp makes an angle of ? = 30.0° as shown in the figure. The coefficient of kinetic friction is 0.360 for both blocks. (c) Determine the tensions in the string on both sides of the pulley.
