Question:
All conditions of Prob. 5/207 remain the same, except the counterclockwise angular velocity of crank OA is 10 rad/s when θ = 0 and the constant counterclockwise angular acceleration of the crank is 20 rad/s2. Determine and plot as functions of the crank angle θ the angular velocities of bars AB and BC over the range 0 ≤ θ ≤ 360°. State the maximum absolute value of each angular velocity and the value of θ at which it occurs.

Angular movements are produced when the angle between the bones of joint changes. There are several different types of angular movements, including flexion, extension, hyperextension, abduction, adduction, and circumduction. Flexion, or bending, occurs when the angle between the bones decreases. Moving the forearm upward at the elbow or moving the wrist to move the hand toward the forearm are examples of flexion. The extension is the opposite of flexion in that the angle between the bones of a joint increase.
