GEORGIA PERIMETER COLLEGE - FALL 2008 Torque and Equilibrium seek laboratory participator: Luan Truong Physics Lab 2211 Section 265 Professor pile M. Duke Lab # 7 Torque & Equilibrium realise Performed: 10/16/08 Date Submitted: 11/06/08 Purpose: In this lab, we impart use the principles of rotational residue, center of gravity, and torque to create a simple visual modality scale using a meter stick to expect the torques produced by various weights. Principles: The succeeding(a) principles were used in this lab: Principles of Static equilibrium, Principles of rotational equilibrium Newtons Second right of Motion implication of force. Method of moments. Performance of the Experiment: The experiment was performed in union with the instructions in the Lab manual with the following exceptions: no(prenominal) Preliminary Data: mystical mass 63.82g fix/hanger pile: hug 1. 16.75g Mass of meter stick: 114.21gClamp 2. 16.71g Hangar 1. 5.21g aggregate of gravity 49.92cm (meter stick) isolated Mass (Method of Moments) m1 121.87g x0 49.92cm x1 30.1cm -19.92cm x2 78.81cm 28.81cm m2 84.26g stranger mass 62.30g Δm2 .009g per centum error 2.

38% Calculations: -Which uncertainty has the greater heart and mortal? All the uncertainty had the same effect. -Does the measured value place within your range of error? No, but very close. = (121.87g/1000g )(9.8)(-19.92/100) =.-238Nm =(84.26/1000g )(9.8)(28.81/100) =.238Nm = = 84.26g Unkno wn mass = m2-mass of hangar- mass of clamp ! =84.26-5.21-16.75 = 62.30g Percent error = (experimental actual)/ (actual) x 100 = 100[(62.30-63.82) / (62.30)] = 2.38% Δm2 = = =.0082 +.0005+.0003 = .009 Meter Stick Mass (Method of Moments) m1 122.19g x0 39.79cm x1 30.1cm -9.69cm xs 49.92cm...If you want to go away a full essay, order it on our website: OrderEssay.net
