Acarnival ride is designed to allow the general public to experience high acceleration motion. the ride rotates about point o in a horizontal circle such that the rider has a speed v0. the rider reclines on a platform a which rides on rollers such that friction is negligible. a mechanical stop prevents the platform from rolling down the incline. the carnival ride is modified so that 80 kg riders can move up and down the inclined wall as the speed of the ride increases. know that the coefficient of static friction between the wall and the platform is 0.29. determine the range of values of the constant speed v0for which the platform will remain in the position shown. (round the minimum velocity, vmin to three decimal places and the maximum velocity, vmax to two decimal places.)

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
