A homogeneous pulley with two grooves consists of two wheels which turn together as one around the same axis. The moment of inertia of the two wheels together is ICM = 40 kg m2. The radii are: R1 = 1.2 m and R2 = 0.4 m. The masses that hang on both sides of the pulley are m1 = 36 kg and m2 = 12 kg. We will assume that the masses of the ropes are negligible. Determine the angular acceleration of the pulley, acceleration of the masses, and the tensions of the ropes.
A string is wrapped around the central axis of a platform that is free to rotate. A 100 g mass attached to the string falls, exerting a torque on the spinning platform. The empty platform has a rotational inertia of 1.75 g·m2. Two masses, m1 = 25 g and m2 = 35 g, are attached to the top of the platform a distance of 15 cm from the central axis. Once the 100 g mass falls a distance of 1.31 m, the string detaches from the central axis. At this point the 100 g mass is moving downward at a speed of 0.96 m/s. Find the maximum rotational speed of the rotating platform with masses m1 and m2 attached.
A three-blade wind turbine, which spins perpendicularly to the ground, is set on a pole that is 38 m tall and completes 5 revolutions in one minute. The length of one blade is approximately 4 m long.

There is a clever kitchen gadget for drying lettuce leaves after you wash them. It consists of a cylindrical container mounted so that it can be rotated about its axis by turning a hand crank. The outer wall of the cylinder is perforated with small holes. You put the wet leaves in the container and turn the crank to spin off the water. The radius of the container is 12.2 cm. When the cylinder is rotating at 2.45 revolutions per second, what is the magnitude of the centripetal acceleration at the outer wall? Number Units #
In a lab experiment, a student brings up the angular speed of a flywheel to 50 rpm. She then allows the flywheel to slow down on its own and counts 85 revolutions before it comes to a stop. The rotational inertia of the flywheel is 0.095 kg·m². What is the retarding torque on the flywheel? (rpm = rev/min)

A horizontal circular platform rotates counterclockwise about its axis at the rate of 0.947 rad/s. You, with a mass of 65.7 kg, walk clockwise around the platform along its edge at the speed of 1.09 m/s with respect to the platform. Your 20.1 kg poodle also walks clockwise around the platform, but along a circle at half the platform's radius and at half your linear speed with respect to the platform. Your 17.9 kg mutt, on the other hand, sits still on the platform at a position that is 3/4 of the platform's radius from the center. Model the platform as a uniform disk with mass 91.1 kg and radius 1.95 m. Calculate the total angular momentum of the system. total angular momentum: kg · m?/s
