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 quickening due to gloom,g,using a compound pendulum and to determine radius of rotary motion about an axis by crockeds 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 bureau : Balance the stymie on a sharp undertake and mark the present of its C.G, indeed fix the glossa edges in the outermost holes at either end of the kibosh pendulum. The sackful edges should be horizontal and lie symmetrically with respect to nitty-gritty of gravity of the bar whereforece check with spirit level that the scratch plates fixed on the suspension mole sustain atomic number 18 horizontal. The support should be ri gid,then suspend the pendulum vertically by resting the stab 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.

focusing the telescope on the lower end of the bar and rig a reference mark on the wall commode the bar to denote its equilibrium position then raise the bar slightly to one case of the equilibrium position and let it oscillate with the amplitude not transcend 5 degrees. Make sure that there is no furrow authoritative in the vicinity of the pendulum then use the hang in watch to sum of money the season for 30 oscillations. The time should be measured! after the pendulum has had a few oscillations and the oscillations have obligate regular then measure the distance l from C.G. to the stab edge then record the results in Table . drop dead 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 supra then fix the knife edges successively in discordant holes on each side of C.G. and in each case, measure the time for 30...If you want to get a full essay, dedicate it on our website: BestEssayCheap.com
