1. Balance the meter stick across the ring stands.

2. Calibrate the scale.

3. Weigh the second largest hook in grams.

4. Record the mass of the second largest hook.

5. Situate the second largest hook 0.20 meters

away from the center of the meter stick (0.50

meters) OR simply place the hook at 0.70 meters.

6. Determine the hook that would be suitable to

reach rotational equilibrium.

7. Weigh the chosen hook and record the mass in grams. For this experiment, the desirable hook weighs 47 grams.

8. To complete mathematical equations accurately, convert each hook's mass from grams to kilograms. Ex: 47 g=0.047 kg

9. Use the equation below to solve for the appropriate lever arm for the second hook.
