**Activity: Drawing a Free Body Diagram**

**Instructions:**

12. *Task:* Draw a free body diagram of the meter stick in the space provided below. Make sure to correctly indicate where on the meter stick each force acts. Be sure to include the weight of the meter stick and the weight of the metal clamp!

#### Diagram Explanation:

- **Meter Stick:** The diagram shows a horizontal meter stick.
- **Pivot Point:** On the left end of the meter stick, labeled as the "pivot point."
- **Forces:** 
  - **V:** An upward arrow labeled "V," indicating a vertical force acting upward at the pivot point.
  - **H:** A horizontal arrow pointing right, labeled "H," indicating a horizontal force.
- **Measurement Indicator:** The center of the stick is labeled "X CM," indicating a certain position along the meter stick.
- **Metal Clamp:** Located towards the right end of the meter stick, represented by a gray rectangle.
- **Rope:** A rope is shown as an angled line attached to the metal clamp, extending upwards and to the right.

Be sure to identify the locations where the forces act on the diagram and annotate them with the appropriate force vectors. Consider gravitational forces acting on both the meter stick and the metal clamp.

**Objective:** Understanding how different forces interact with objects in a static equilibrium setup.

**Instructions:**

6. Repeat steps 2-5 for a force probe height of 90 cm, 80 cm, 70 cm, 60 cm, and 50 cm.

7. Remove the metal clamp from the meter stick and measure its mass. Record the result below.

   Mass of the metal clamp = ________ grams (22.5 grams noted).

8. What was the distance between the pivot point and the metal clamp (where the force of tension acts) in this experiment? Record the distance below.

   \( r = \) ________ cm (90 cm noted).
