Compund Pendulum

OBJECT: To study the properties of a compound pendulum, and to determine the speed up due to gravity by the use of such a pendulum. METHOD: An experimental pendulum is suspended successively more or less some(prenominal) axes at different points along its continuance and the blockage consonant about each bloc is observed. A graph is plotted of the period versus the infinite of the axis of suspension from sense experience end of the pendulum. The personality of the graph shows the physical properties of the compound pendulum. From determine of the period and the be length of the equivalent simple pendulum as determined from the graph, the quickening due to gravity is calculated. From the good pass over of the pendulum and its radius of gyration as obtained from the curve, the rotational inertia of the pendulum is computed. opening: A simple pendulum consists of a small ashes called a bobsleigh (usually a sphere) attached to the end of a string the length of wh ich is great compared with the dimensions of the bob and the mass of which is negligible in similitude with that of the bob. Under these conditions the mass of the bob may be regarded as concentrated at its center of gravity, and the length l of the pendulum is the outer space of this point from the axis of suspension.

When a simple pendulum swings through a small arc, it executes running(a) simple harmonic motion of period T, given by the equation T = 2? ?(l/g) (1) where g is the acceleration due to gravity. This relation-ship affords one of the simplest and most satisfactory methods of determining g experimenta lly. When the dimensions of the suspended b! ody are not negligible in comparison with the distance from the axis of suspension to the center of gravity, the pendulum is called a compound, or physical, pendulum. either body mounted upon a swimming axis so as to vibrate under the take out of gravity is a compound pendulum. The motion of such a body is an angular vibration about the axis of suspension. The expression for the period of a compound pendulum may be...If you want to redeem a expert essay, order it on our website: BestEssayCheap.com
