Question
The uniform 24-m robotic arm OB weighs 300 kg and is hinged at its lower end to a fixed
support at O. If the actuator C develops a starting torque of 1300 N· m, calculate the total force
supported by the pin at O as the arm begins to lift off its support at B. Also find the
corresponding angular acceleration a of the robotic link. The cable at A is horizontal, and the
mass of the pulleys and the actuator is negligible. (see Figure 2)
