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

### Transcription for Educational Content:

**Description:**

The diagram shows two muscles in the back of the leg, each applying a force of 200 N at a 20-degree angle from the vertical axis towards the Achilles tendon.

**Text:**

"Two muscles in the back of the leg pull upward on the Achilles tendon. Find the magnitude and direction of the total force on the Achilles tendon. What movement is caused by this force?"

**Diagram Explanation:**

- The illustration features a simplified cross-section of a leg showing the location and orientation of muscles and the Achilles tendon.
- There are two muscle forces depicted on either side of the tendon.
- Each muscle exerts a force labeled \( F \) (200 N) at a 20-degree angle from the tendon.
- The arrows indicate the direction of each force, pulling towards the center.

**Key Concepts:**

- **Vector Addition:** The forces are at angles and need to be combined using vector addition to find the resultant force.
- **Components of Force:** Each force has vertical and horizontal components, which can be calculated using trigonometric functions.
- **Resultant Force Calculation:** By summing the components, you determine the net force acting on the Achilles tendon.

A skydiver weighing 65 kg jumps out of a helicopter hovering at a height of 3 kilometers. Assume a cross-sectional area of 0.5 square meters. After thirty seconds of free fall, the skydiver deploys the parachute and the cross-sectional area becomes 40 square meters. Reproduce the model for the skydiver in Excel or VenSim. In VenSim you may have to make At quite small in order not to throw an error. Because you reach terminal velocity relatively quickly your answer should not be particularly sensitive to the value of At you choose. What is the skydiver's terminal velocity without the parachute? meters/second What is the skydiver's terminal velocity with the parachute? meters/second
