In an amusement park ride, riders stand against the vertical wall of a spinning cylinder. The floor falls away and the riders are held up by friction. If the radius of the cylinder is R, find the minimum number of revolutions per time necessary if the coefficient of friction between a rider and the wall is given.
Q1
A carnival ride has people stand inside a vertical cylinder with their backs to the wall. The cylinder starts spinning and the riders find that they are “stuck” to the wall and don’t slide down, even if the floor is removed. The ride has a radius of r. The person has a mass of m and is moving with a constant speed of v. The coefficient of static friction between the person and the wall is μs , and kinetic friction μk. The person is only touching the wall, not touching the floor. What is the magnitude of the acceleration of the person? In what direction does it point? The speed is constant. Why is the acceleration not zero? Briefly explain. No equations!

Two bodies is connected in point C, are supported by rigid underlay at an angle α. F is the force acting on right body. We are considering the weight of bodies G and the friction between the bodies and the underlay. Length of bodies l=2000mm.    G1= 160 N, G2= 180 N, α = 30° Find:  1.) Find the magnitude of the force so that it slips on the underlay 2.) Draw the dependence of the force F as a function of the coefficient of friction f (in the range 0-0.5)
A friction sample is placed on a test ramp that pivots about Point O. When the end of the ramp is lifted to h = 1.2 ft the sample just begins to slide. With L = 3.5 ft, the coefficient of static friction is best given by a. 0.286 b. 0.481 c. 0.365 d. 0.181 O L -W h
2) After playing a game of pinball, you decide to do some calculations on the launching mechanism. The pinball and the plunger have a mass of 0.30 kg and 0.50 kg respectively. The spring coefficient in the pinball machine is 300 N/m. The original length of the spring is 100 mm and the compressed length is 35 mm. If the coefficient of friction between the ball and the surface is 0.15, calculate the velocity of the ball right before it loses contact with the plunger (in m/s). Note that the plunger is never in contact with the ground and assume the ball slides without rolling. [Ans. to check: 1.23 m/s] HO www
