Disk brakes, such as those in your car, operate by using pressurized oil to push outward on a piston. The piston, in turn, presses brake pads against a spinning rotor or wheel, as seen in (Figure 1). Consider a 10 kgkg industrial grinding wheel, 26 cmcm in diameter, spinning at 800 rpmrpm. The brake pads are actuated by 2.0-cmcm-diameter pistons, and they contact the wheel an average distance 12 cmcm from the axis.If the coefficient of kinetic friction between the brake pad and the wheel is 0.60, what oil pressure is needed to stop the wheel in 6.0 ss?
