A 40-kg flywheel of radius R = 0.5 m is rigidly attached to a shaft of radius r = 0.05 m that can roll along parallel rails. A cord is attached as shown and pulled with a force P. Knowing the centroi- dal radius of gyration is k = 0.4 m and the coefficient of static friction is m, = 0.4, determine the largest magnitude of force P for which no slipping will occur. 15° R
