Instructions for Use Part A Change the values in the highlighted cells so that the virtual meter stick in Cases A1 and A2 below are level. The position x represents where the mass is on the meter stick, not the moment arm. Once balanced, use the standard Exp. 9 Template to calculate moment arms and torques (assuming the pivot is exactly at 50 cm). The other positions are fixed. Part B Change the value of the pivot position until the virtual meter stick in Case B below is level. Once balanced, use the standard Exp. 9 Template to calculate moment arms, masses m. and m. and the resulting torques assuming a constant linear mass density. Part C First, change the value C to find the center of mass of the loaded meter stick in Case C (no m ) by balancing the virtual meter stick. Then, set your position for m and rebalance the virtual meter stick in Case C (m added) by moving the pivot position to B. Once balanced, use the standard Exp. 9 Template to calculate moment arms and torques
