The slender L-shaped bar ABCD mass 15 kg/m is free to rotate about thepin at B. The spring connected to the bar at A has a free length of 7 ft, and itsstiffness is 180 N/m. If the system is released from rest in the position shown,determine the angular velocity of the bar when A is directly above B.
6/209 The nose-wheel assembly is raised by the applica- tion of a torque M to link BC through the shaft at B. The arm and wheel AO have a combined weight of 100 lb with center of mass at G, and a centroidal ra- dius of gyration of 14 in. If the angle 0 = 30°, deter- mine the torque M necessary to rotate link AO with a counterclockwise angular velocity of 10 deg/sec that is increasing at the rate of 5 deg/sec every second. Additionally, determine the total force sup- ported by the pin at A. The mass of links BC and CD may be neglected for this analysis. - 16"- B 20" C 32" 20" Problem 6/209
