Question

Ppte side of the fulcrum so that it balances the system ehboset ever arm is significantly different from the unknown mass lever arm). 0Wh mass such that its is signi ecord the known mass and both lever arms in table 3. epeat steps 17 and 18 with a different known mass. 18. R 19. R 20. Calculate the moment from the 21. Calculate the unknown mass. 22. Weigh the unknown mass on a balance to measure its mass. 23. Calculat known mass, and determine the moment from the unknown mass. e the %error of the determined mass from step 18 compared to the actual mass from step 19 Prelab: What are the two conditions for equilibrium of a rigid body? How would this experiment demonstrate their validity? Why do you not need to take into consideration the force exerted on the meter stick by the support? In part 3, you can calculate the moment of the known mass and use that to determine the unknown mass, but explain how the unknown mass can be determined without directly calculating the torque Chint: use ratios). What defines the center of gravity of a rigid body? How does it relate to center of mass? 1. 2. 3. 4. 5. Assume a 150g meter stick with center of mass at the 48cm mark is supported by the 60cm mark. There are two masses placed on the meter stick; mi=50g and is placed at the 16cm mark and m2 is induced by each of the masses (don't forget about the mass of the stick itselfi)? Now, supposing m2is located on the 100cm mark, what must its mass be? What if it is at the 80cm mark? an unknown mass at an undisclosed location. The meter stick is in equilibrium. What is the torque
