Case (4): (1) Calculate theoretically the lever arm () for the mass my = 0.10 kg for the system to be in equilibrium if m=0.30 kg is at the ri = -0.10 m position and m2 = 0.10 kg is at the r2 = +0.40 m position. (ii) Check your results experimentally, and compute the percent error of the experimental value of r3, taking the previously calculated value as the accepted value. Record this value in the data table (ii) Check your results experimentally, and compute the percent error of the experimental value of ry, taking the previously calculated value as the accepted value.Ĭase (4c): (i) Calculate theoretically the lever arm (r) for the mass my=0.10 kg for the system to be in equilibrium if m=0.20 kg is at the r=-0.10 m position and m2 = 0.20 kg is at the r2 =+ 0.30 m position. Case (4b): (1) Calculate theoretically the lever arm (r) for the mass m = 0.05 kg for the system to be in equilibrium if m=0.10 kg is at the r=-0.30 m position and m = 0.20 kg is at the 12 = +0.10 m position. Record the masses and moment (ii) Compute the torques and compare as in Procedure 3. position ra) of a mass my = 0.20 kg suspended on the right side of the meter stick. (ii) Set up the conditions for static equilibrium by adjusting the moment arm (i.e. Two known masses Case ( 3a): b) With the meter stick on the support stand at X, suspend a mass m, 0.10 kg at the r = -0.35 m position on the meter stick-that is, 0.35 m on the left side of the meter stick's center point. This location is the center of mass (com) and center of gravity (cog) of the meter stick.

With the meter stick balanced on its support stand, note its balancing point (X.), as measured from the zero end of the meter stick.

Suspend m=0.05 kg and adjust the moment arm of this mass so that the meter stick is in static equilibrium. Record this average mass above Data Table 1 Case (4a): (i) With the meter stick on the support stand at Xo, suspend m = 0.10 kg at the 11 =-0.20 m position and m:= 0.20 kg at the 12 = +0.20 m position. Three known masses: (ii) In order to account for the mass of the weight hangers, weigh all the hangers together on your scale and compute the average mass of one hanger. (ii), and (iii) from Case ( 3a), but now with mass m = 0.20 kg at the n = -0.25 m position on the meter stick, and m=0.30 kg. () Determine the mass of the meter stick and record it above Data Table 1. The string allows the position of a mass to be read easily. Various masses will be placed in weight hangers, which will then be suspended from small loops of string that are attached to the meter stick. Apparatus with Support Point at Center of Gravity 1.
