A motorcyclist in a circus rides his motorcycle within the confines of the hollow sphere. The coefficient of static friction between the wheels of the motorcycle and the sphere is μ = 0.5. The mass of the motorcycle and rider is 250 kg, and the radius of curvature to the center of gravity is ρ = 20 m. Neglect the size of the motorcycle for the calculation. (a) Determine the minimum speed at which he must travel if he is to ride along the wall when θ = 90∘. Express your answer to three significant figures and include the appropriate units.

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?
