Non- Parallel Forces on the Non- Concurrent Force Apparatus Source of Torque Force Sensor #1 Force Sensor #2 Weight of Apparatus Weight of 500-g Load Amount of Force () F 1 6.4N F 2 7.3N W app 8.6N W load 4.8N Position of Force () X 1 .06m X 2 .41m X CG experimental: .309m X 4 .15m X CG measured: .285m Direction of Force () Θ 1 83° Θ 2 67° Θ 3 73° Θ 4 73° Percent Error in Experimental Center of Gravity for Non-Parallel Forces : 8.42%
Data Analysis : X cg (experimental)=(X 1 F 1 + X 2 F 2 - X 4 W load ) / W app Table 1 : X cg (experimental)=((.06m)(6.7N) + (.41m)(7.0N) - (.15m)(4.8N)) / (8.6) = .297 Percent Error: ((measure-experimental)/measured) * 100% ((.285-.297)/.285) * 100% = 4.21% Table2 : X cg (experimental)=((.06m)(6.4N) + (.41m)(7.3N) - (.15m)(4.8N)) / (8.6) = .309 Percent Error: ((measure-experimental)/measured) * 100% ((.285-.309)/.285) * 100% = 8.42%
