Question

can ignore friction when they ispherical bowl of II. A) In this part of the laboratory you will explore the basic concept of rotational equilibrium, i.e. the balancing of torques about a fulcrum or pivot point. You will be given values for 3 masses along with given positions (X) on a meter stick for which two of these masses will be hung. Your task is to determine the position that the third mass must be hung in order to balance the meter stick, i.e. achieve rotational equilibrium. The location of the center of mass of the meter stick (its pivot point) will be determined by balancing the meter stick without masses added Xem 50 g@ 15 cm to left of the center of mass; M2- 100g@35 of mass; determine where to put Ms 150 g to balance as reference from the center of mass of the stick. Show your calculations here: МI ст cm to the left of the center X3= to the LEFT RIGHT of the Center of Mass. Now test out your calculations with your meter stick balance. Briefly describe the results of your test here. 3. What is the mass placement for section II, part A) of this lab experiment? Assume the Center of um M2= 100g 35nt Mass is at the 50 Mi-50 cm mark. M3-150g @? IScm 36Um SOm
