You are designing a system for moving aluminum cylinders from the ground to a loading dock. You use a
sturdy wooden ramp that is 2.00 m long and inclined at 37.0° above the horizontal. Each cylinder is fitted with
a light, frictionless yoke through its center, and a light (but strong) rope is attached to the yoke. Each cylinder is
uniform and has mass 410 kg and radius 0.300 m. The cylinders are pulled up the ramp by applying a
constant force F to the free end of the rope. F is parallel to the surface of the ramp and exerts no torque on

a. Create a free body diagram of the above condition and apply the sign convention for forces and moments.
b. Calculate the magnitude of the compression force (F compression) and shear force (F shear) generated.
c. Analyze whether the work is safe to perform.

This is an example diagram of Atwood’s Machine. This machine works by hanging two masses on a pulley, with each mass being acted upon by gravity. Since the masses are on opposite sides of the pulley, their weights oppose each other, and the net acceleration is less than g. To see this, please draw in all of the relevant forces in the diagram below. Be sure to indicate which direction friction in the pulley is acting. Assume m1 > m2.

A heavy cask (full of wine!) sits on an inclined plane. It is held in place by a rope that is attached to the cask and to a hook further up the inclined plane (at A). The rope comes off of the cask tangent to the cask. The mass of the cask is 40 kg, and the coefficient of static friction between the inclined plane and the cask is 0.25. What is the maximum value of θ just before the cask begins to slip? Also, what is the tension in the rope when slipping is impending? Finally, if the inclined plane became icy, and the rope didn’t break as the cask slipped, what would be remarkable about the lines of action of the W, N and T force vectors once equilibrium was re-established?

Instead of using the system shown in Figure.a to raise the mass m2, an engineer proposes to use two simple machines, the pulley and the inclined plane, to reduce the weight required to lift m2. The proposed design is shown in Figure.b. The pulley inertias are negligible. The available horizontal space limits the angle of the inclined plane to no less than 30°. Suppose that the friction between the plane and the mass m2 is negligible. Identify the equation to determine the smallest value m1 that can lift m2. (The answer should be a function of m2 and θ.)
