If all frictional effects are neglected, the expression for the angular acceleration of the simple pendulum is
Question:
If all frictional effects are neglected, the expression for the angular acceleration of the simple pendulum is θ¨ = g/l cos θ, where g is the acceleration of gravity and l is the length of the rod OA. If the pendulum has a clockwise angular velocity θ˙ = 2 rad/s when θ = 0 at t = 0, determine the time t′ at which the pendulum passes the vertical position θ = 90°. The pendulum length is l = 0.6 m. Also plot the time t versus the angle θ.

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.
