Most injuries to the shoulder will require rehab and physical therapy. Pendulum exercises are a great way to increase strength and improve flexibility and range of motion in an injured shoulder. Here, the patient bends forward until their back is horizontal. The injured arm is hung vertically downward and is allowed to swing freely back and forth like a pendulum (see the figure). Treat the arm (length of 69 cm) in the figure as a physical pendulum – a uniform rod rotating about an axis through one of its ends – and calculate the period of the arm’s small oscillations.

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.
