A special pulley has two hubs where two different strings wrap around either hub. The pulley has total moment of inertia I= 1.6 kg m^2. The smaller hub has radius r1=8cm, and the string wrapped around this hub connects to the mass m1= 200kg. This mass rests on a frictionless plane incline at angle 0=30. The second string wraps around the larger hub with radius r2=25cm and connects to a freely hanging mass m2=25 kg.

Determine the angular acceleration of the pulley and sense of rotation once the system is allowed to move freely. The string do not slip on their respective hubs.

    Two blocks are connected by massless string that is wrapped around a pulley. Block 1 has a mass m1=5.30m1=5.30 kg, block 2 has a mass m2=2.50m2=2.50 kg, while the pulley has a mass of 1.60 kg and a radius of 14.1 cm. The pulley is frictionless, and the surface mass 1 is on is also frictionless. If the blocks are released from rest, how far will block 2 fall in 2.60 s?

    A thick walled cylinder has a light string wrapped around its outer radius and rotates about a horizontal axis. The string then goes vertically straight up and over a massive pulley that also rotates about a horizontal axis, and finally connects to a mass m = 0.900 kg on a rough incline (μk = 0.200) that is angled at 25.0° to the horizontal. When the system is released from rest the mass slides down the ramp a distance of 1.80...
