Question: The nose-wheel assembly is raised by the application 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 radius of gyration of 14 in. If the angle Θ = 30°, determine 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 supported by the pin at A. The mass of links BC and CD may be neglected for this analysis. Answer : Draw the schematic diagram of the system for the link .
