3. The wooden spool has a weight of (: 221 ) lb and a radius of gyration of 12 inches about its center of mass. The coefficients of static and kinetic friction are 0.20 and 0.15, respectively, between the spool and the horizontal surface. (a) Determine the angular acceleration of the spool and the acceleration experienced by the cable if P = (1 121_1) lb. (b ) Calculate the maximum allowable force P and the corresponding angular acceleration to prevent slipping of the spool. B P G 10 in 16 in A
