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.
Question Four forces (measured in Newtons) act on a crate. The forces are given by the vectors: F₁ = 2121-136ĵ+ 241k N, F₂ = 108î+ 144) + 189k N. F3 = -400 + 180) + 240k N, and F₂ = -270k N Given: The magnitude of the resultant force = 449.2 N. The work done by the force F is 770.3J.

Determine the magnitude of the force that you need to exert on the end of the stick (perpendicular to it) so that the cylinder moves with a constant speed. Determine the work done by your hand on the stick while your hand makes one full turn around the axis. Determine the work done by the stick on the cylinder during the one full term around the axis.
