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

**Text:**

The arm in the figure below weighs 35.1 N. The force of gravity acting on the arm acts through point A. Determine the magnitudes of the tension force \( \vec{F_t} \) in the deltoid muscle and the force \( \vec{F_s} \) exerted by the shoulder on the humerus (upper-arm bone) to hold the arm in the position shown. (Enter your answers to at least the nearest newton.)

\( F_t = \) ______ N

\( F_s = \) ______ N

---

**Diagram:**

- The diagram shows an arm extended horizontally, aligned parallel to the axis.
- A force \( \vec{F_t} \), representing the tension in the deltoid muscle, is depicted as an arrow pointing horizontally to the left.
- Another force \( \vec{F_s} \) is shown as an arrow pointing diagonally upwards towards the left, forming an angle of \( 12^\circ \) with the horizontal axis.
- The force of gravity \( \vec{F_g} \) is shown acting downwards from point A on the arm.
- The distance from the axis point O to point A is labeled as 0.290 m.
- The distance from the axis to the point where \( \vec{F_t} \) acts is 0.080 m.
