Part I. Indicate the total masses (including clamps/hangers) and their locations on the meter stick for Part I. 220g for clamp total @15cm @65 cm adding_430_ for equilibrium so i added 430 g with addition on the hanger and clamp 50g and 20g so the total for weight of clamp is 500G FLeft (N) RLeft (m) T CCW = + F R (m.N) Left Left Fright (N) Compare the clockwise and counterclockwise torques Answer here Rright T (m) CW == F R Right Right (m.N)
1. Familiarize yourself with the apparatus by exploration (and consulting the document from KET Virtual Physics Labs). You will not need any balloons or pulleys for this activity, but you will we be adjusting the positions of the clamps and the fulcrum and adding/subtracting massed from the hangers. It is convenient to check the "Auto-Release" button which makes it easy to assess whether you've achieved equilibrium while also making it easy to make additional changes. Key information: the clamps have a mass of 20g and the hanger mass is 50g 2. With the fulcrum at the center (50cm), place a clamp at the xcc = 15 cm position and hang 200 g from it. Recall the hanger is 50g of that total and that with the clamp the total downward force at this position will be (220g)*g. 3. Place another clamp at the xc = 65.0 cm position. Add enough mass to attain equilibrium. If small. If you lose track of how much mass is on the hanger you can just click on the masses to see the total you have added in the box. You can remove mass by right-clicking (ctrl-clicking) on the masses. When you've achieved equilibrium (within +/- 2%) the beam will remain balanced (not rotate one way or the other) and a note appears in the text box. 4. From you masses, determine the downward force at each location, the appropriate lever arm for each force and the torque due to these forces. Treat ccw torque as positive. 5. Compare the clockwise and counterclockwise torques.
