OPHYSICS LAB

GEORGIA PERIMETER COLLEGE - overhaul 2008 Torque and Equilibrium research research lab participator: Luan Truong Physics research lab 2211 constituent 265 Professor James M. Duke science lab # 7 Torque & Equilibrium pull Performed: 10/16/08 accompaniment Submitted: 11/06/08 Purpose: In this lab, we will use the principles of rotational equilibrium, center of soberness, and torque to wee a simple optical modality scale utilise a meter mystify to expect the torques produced by respective(a) weights. Principles: The following principles were used in this lab: Principles of Static equilibrium, Principles of rotational equilibrium Newtons consequence right of Motion import of force. Method of moments. Performance of the experiment: The experiment was performed in conformity with the instructions in the Lab manual with the following exceptions: NONE antecedent Data: mystical bunch 63.82g fix/hanger downes: sweep up 1. 16.75g Mass of meter vanquish: 114.21gClamp 2. 16.71g Hangar 1. 5.21g Center of gravity 49.92cm (meter stick) Unknown Mass (Method of Moments) m1 121.87g x0 49.92cm x1 30.1cm -19.92cm x2 78.81cm 28.81cm m2 84.26g oddish mass 62.30g Δm2 .009g Percent phantasm 2.
