A motorcyclist in a circus rides his motorcycle
within the confines of the hollow sphere. If the coefficient of
static friction between the wheels of the motorcycle and the
sphere is µ, = 0.4, determine the minimum speed at which
he must travel if he is to ride along the wall when e = 90°.
The mass of the motorcycle and rider is 250 kg, and the
radius of curvature to the center of gravity is p = 20 ft.
Neglect the size of the motorcycle for the calculation.
The crate has a mass of 80 kg and is being towed by a chain which is always directed at 70° from the vertical. The towing force is defined by the equation: P = 20t², where P is in Newtons and t is in seconds. If the coefficient of static friction is µ = 0.4 and the coefficient of kinetic friction is k 0.3, evaluate the = time when the crate's acceleration is 1.7473 m/sec². Apply Newton's second law of motion.
The man is pedaling his bicycle at a constant speed up a slippery slope of 5%. The man and the bicycle have a total mass of 82 kg centered at G. If the rear wheel is about to slip, find the coefficient of friction u between the tire and the road. If the coefficient of friction were doubled, what friction force would act on the rear wheel? (Why can we neglect the friction under the front wheel?)
