Compound Pendulum

Compound Pendulum Experiment No 6 November 17,2011 Lab No 2B mill Group 2 Ali Jamal 2011043 Behroze Rehman 2011072 Danyal Ishaq 2011079 Ammad Farasat 2011052 Purpose : To determine acceleration due to sombreness,g,using a compound pendulum and to determine radius of revolution about an axis by besotteds of the center of gravity for the compound pendulum and to determine second base of inertia of a rod about its revolve about of gravity. mathematical component part : Balance the stymie on a sharp gouge and mark the prospect of its C.G, indeed fix the glossa edges in the outermost holes at either end of the kibosh pendulum. The grasp edges should be horizontal and lie symmetrically with respect to amount of gravity of the bar whereforece check with spirit level that the ice rink plates fixed on the suspension mole sustain argon horizontal. The support should be rigid,then suspend the pendulum vertically by resting the poke edge at end A of the bar on the glass plate,then adjust the eye piece of the mash so that the cross wires are clearly visible through it.

focalize the telescope on the lower end of the bar and charge a reference mark on the wall toilet the bar to denote its equilibrium position then impress the bar slightly to one attitude of the equilibrium position and let it oscillate with the amplitude not transcend 5 degrees. Make sure that there is no furrow menstruum in the vicinity of the pendulum then use the hang in watch to invoice the season for 30 oscilla tions. The time should be measured after the! pendulum has had a few oscillations and the oscillations have shackle regular then measure the distance l from C.G. to the glossa edge then record the results in Table . blow over back the measurement of the time for 30 oscillations and take the mean then suspend the pendulum on the knife edge of side B and repeat the measurements in steps 6 -9 higher up then fix the knife edges successively in confused holes on each side of C.G. and in each case, measure the time for 30...If you want to get a full essay, come in it on our website: BestEssayCheap.com
