2: 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. What is the maximum value of angle theta before the cask begins to slip? Also, what is the tension in the rope when slipping is impending? The mass of the cask is 60 kg, and the coefficient of static friction between the inclined plane and the cask is 0.3. Finally,
if the inclined plane became icy, and the rope didn’t break as the cask slipped, what would be common about the lines of action of the W, N and T force vectors once equilibrium was reestablished? Hint: draw a FBD.
