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...

Constants| Periodic Table Part A In the figure the lower disk, of mass 430 g and radius 3.1 cm, is rotating at 180 rpm on a frictionless shaft of negligible radius. The upper disk, of mass 270 g and radius 2.5 cm, is initially not rotating. It drops freely down onto the lower disk, and frictional forces bring the two disks to a common rotational speed. (Figure 1) Find the final common frequency in rpm. Express your answer using two...

A grindstone in the shape of a solid disk with diameter 0.520 m and a mass of 50.0 kg is rotating at 800 rev/min. You press an axe against the rim with a normal force of 160 N (see the figure below), and the grindstone comes to rest in 7.00 S. (Figure 1) Part A Find the coefficient of kinetic friction between the axe and the grindstone. There is negligible friction in the bearings Express your answer to three significant...

Constants Part A To get a flat, uniform cylindrical satellito spinning at the correct rate, engineers fire four tangential rockets as shown in the figure (Figure 1). Suppose that the sateilite has a mass of 1400 kg and a radius of 3.3 m,and that the rockets each add a mass of 250 kg. What is the steady force required of each rocket if the satellite is to reach 32 rpm in 2.5 min, starting from rest? Express your answer to...
