1. The problem statement, all variables and given/known data Hey y'all. Heres the problem: The flywheel to the right is spinning at 300 radians per second in a counter clockwise direction. The brake (to the left) is applied with a force F of 5kN. How long will it take the flywheel to stop rotating? Assume: The flywheel is made of steel The units above are in cm The brake disc uses all the friction surface area on the flywheel 2. Relevant equations Here are the relevant equations: Friction: 2500 N Area of friction plate: 0.1018 m^2 Torque (brake): 2250 N.m Inertia (don't have mass): 3. The attempt at a solution I'm fairly stumped at which direction to take. At the moment my attempt goes something like this: 1. working out the area that the disk brake will affect 2. working out the friction force that will be applied from the disk brake to the flywheel 3. the amount of torque the brake has Then somehow linking stuff together... How i imagined the problem: speed of the flywheel --> disk brake is applied --> the friction of the brake to the flywheel will slow it down --> result is it will stop moving. How to get time from all of this baffles me. Any suggestions will be greatly appreciated Thanks for your time in advance!
