Can you please help me with 4-6, I had started 4 & 5 but I am not sure if I have done them correctly based on the numbers.

Mass of Clamp: 20.1g

Mass of Clamp with Hook: 21.7g

Mass of Meter slick: 53.9g

Center of Mass: 25.5 cm

The reading on the spring balance for 7 is 350g, and for 8 is 200g

4. For procedure 7, calculate the upward force provided by the spring balance using the second condition for equilibrium (Torque) and compare with the experimental result by finding the percent difference.

5. For procedure 8, calculate the upward force providedby the spring balance using the second condition for equilibrium (Torque) and compare with the experimental result by finding the percent difference.

6. Check the sum of the two spring balance readings from procedure 7 & 8 against the total weight to verify the first condition for equilibrium (Sum of forces in y direction).

cedure (4), calculate the position of the third clamp using the second condition for equilibrium and compare with the experimental result by finding the percent difference. | Xexpt - X theo -x100% The % difference = X avg Since the force acting on the stick by the fulcrum is unknown, simplify your calculation by calculating the torques about this point. 2. For procedure (5), calculate the position of the second clamp using the second condition for equilibrium and compare with the experimental result by finding the percent difference. By the same reason as in Data Analysis 1, calculate the torques about the fulcrum. 3. For procedure (6), calculate the upward force provided by the fulcrum using the first condition for equilibrium and compare with the experimental result by finding the percent difference. 4 . For procedure (7), calculate the upward force provided by the spring balance using the second condition for equilibrium and compare with the experimental result by finding the percent difference. 5. For procedure (8), calculate the upward force provided by the spring balance using the second condition for equilibrium and compare with the experimental result by finding the percent difference. 6. Check the sum of the two spring balance readings from procedures 7 and 8 against the total weight to verify the first condition for equilibrium. Questions: 1. Describe what the motion of a rigid system will be if: a) The first condition for equilibrium is not satisfied. b) The second condition for equilibrium is not satisfied. c) Neither condition for equilibrium is satisfied. 2. If the numbers of clamps on each side of the support fulcrum are the same, say one and one, can their weight be omitted from the torque calculation? Explain. 3. If three forces act on an extended object and the object is in equilibrium, prove that the lines of action of these three forces intersect at one point. 4. Use two fingers to support a meter stick, one at the 10 cm mark and another at the 65 cm mark. Move the two fingers closer slowly until they meet. Where do the two fingers meet? Repeat with different starting positions for the two fingers and explain the results. 53d clamp. X 10 20 30 40 50 Figure 3 100 g 6. Remove the system from the fulcrum, attach a hook to the knife-edge in the upward position, and suspend the whole system from a spring balance (Figure 4). This will give you the upward force provided by the fulcrum. X 10 20 30 40 50 TTTT Figure 4 100 g 7. Place a clamp with a hanging mass of 300 g at the 30.0 cm mark of the half-meter stick (Figure 5). Place the second clamp at the 5.0 cm mark on the fulcrum and the third clamp at the 40.0 cm mark with a hook upward. Hang the upward hook to a spring balance and find the reading on the balance. Be sure to keep the half-meter stick horizontal. 10 20 50 300 g Figure 5 8. Interchange the spring balance with the fulcrum and read the spring balance. 52
