Design of a fairground attraction
A fairground attraction consists of a flat turntable of 12m diameter on which 4 gondolas are attached. The turntable is at an angle of 7.5 °. The disc rotates at an average speed of 8 rpm, the gondolas in the opposite direction around their own axis at 22 rpm. Each gondola can accommodate 4 people. Design the turntable drive. Approach the disk as a solid round plate with a mass of 26 tons, the gondolas...

A large wooden turntable in the shape of a flat uniform disk has a radius of 2.05 m and a total mass of 130 kg. The turntable is initially rotating at 3.40 rad/s about a vertical axis through its center. Suddenly, a 72.5-kg parachutist makes a soft landing on the turntable at a point near the outer edge. (a) Find the angular speed of the turntable after the parachutist lands. (Assume that you can treat the parachutist as a particle.)...

Constants Part A A solid, uniform cylinder with mass 8.30 kg and diameter 19.0 cm is spinning with angular velocity 205 rpm on a thin, frictionless axle that passes along the cylinder axis. You design a simple friction- brake to stop the cylinder by pressing the brake against the outer rim with a normal force. The coefficient of kinetic friction between the brake and rim is 0.345. What must the applied normal force be to bring the cylinder to rest...
