Problem Type: Find: Given: At the instant shown, the arms of the robotic manipulator have constant angular velocities of ϖ AB = -0.5 rad/s, ϖ BC = 2 rad/s, and ϖ CD = 4 rad/s. The mass of the arm CD is 10 kg, and it’s center of mass is at it’s midpoint. What force and couple are exerted on arm CD at the joint C?

Unformatted text preview: about its center of mass is I = 360 kg-m2. If point A is stationary and the angular acceleration of the arm is 0.6 rad/s 2 counterclockwise, what force does the hydraulic cylinder exert on the arm at B? (The arm has two hydraulic cylinders, one on each side of the vehicle. You are to determine the total force exerted by the two cylinders.) Problem Type: Find: Given:...
