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:**

A person exerts a horizontal force of 190 N in the test apparatus shown in the figure. Find the horizontal force \( \overrightarrow{M} \) that his flexor muscle exerts on his forearm.

**Diagram Explanation:**

The diagram illustrates a side view of a human arm with a focus on the flexor muscle and elbow joint. Key elements include:

1. **Horizontal Force (190 N):** A force applied horizontally at 190 N, depicted pushing against a surface.

2. **Arm Anatomy:**
- **Flexor Muscle:** Indicated in the forearm area, showing where the muscle exerts force.
- **Elbow Joint:** Marked as the pivot point around which torque is calculated.

3. **Measurement Indicators:**
- **0.34 m:** Vertical distance from the point of applied horizontal force to the elbow joint.
- **0.054 m:** Horizontal distance from the elbow joint to the point of force exertion by the flexor muscle.

**Calculation Section:**

- **Number (Input Box):** For entering the calculated force value.
- **Units (Dropdown):** To specify the unit of measurement for the force.

This setup helps understand the biomechanical principles involved in calculating muscle forces using leverage and torque.

The large quadriceps muscle in the upper leg terminates at its lower end in a tendon attached to the upper end of the tibia (see Figure a). The forces on the lower leg when the leg is extended are modeled as in Figure b, where T is the force of tension in the tendon, w is the force of gravity acting on the lower leg, and F is the force of gravity acting on the foot. Find T when the tendon is at an angle of 25.0° with the tibia, assuming that w = 29.0 N, F = 12.3 N, and the leg is extended at an angle ? of 40.0° with the vertical.
