F19–5. The 50@kg spool is subjected to a horizontal force of
P = 150 N. If the spool rolls without slipping, determine its angular velocity 3 s after it starts from rest. The radius of gyration of the spool about its center of mass is kG = 175 mm.
P = 150 N
0.3 m G
F19–3. If rod OA of negligible mass is subjected to the couple moment M = 9 N # m, determine the angular
velocity of the 10@kg inner gear t = 5 s after it starts from rest. The gear has a radius of gyration about its mass center of kA = 100 mm, and it rolls on the fixed outer gear, B. Motion occurs in the horizontal plane.
