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.

Question

**Problem Statement:**

5. The arm in the figure below weighs 39.3 N. The force of gravity acting on the arm acts through point A. Determine the magnitudes of the tension force \( F_T \) in the deltoid muscle and the force \( F_S \) exerted by the shoulder on the humerus (upper-arm bone) to hold the arm in the position shown (magnitude and angle). You can take point O as a reference point.

**Diagram Explanation:**

The diagram shows a horizontal arm with the following components and forces:

1. **Arm Representation:**
- The arm is shown as a straight line extended horizontally.

2. **Forces:**
- \( F_T \): Tension force acting upwards and to the left, forming an angle of \( 12^\circ \) with the horizontal.
- \( F_S \): Shoulder force acting straight upwards.

3. **Measurements and Angles:**
- The angle labeled \( \theta = 8^\circ \) is between the vertical line from the shoulder and the force \( F_S \).
- The diagram also shows a total horizontal length of 0.290 m, with 0.080 m from the shoulder to point A.

**Point O:**
- A reference point marked under the shoulder, from which the forces are considered.

This setup is used to calculate the necessary force magnitudes and the angles to maintain equilibrium of the arm.
