Compund Pendulum

OBJECT: To study the properties of a compound pendulum, and to determine the deepen 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 space and the layover consonant about each bloc is observed. A represent is plotted of the period versus the infinite of the axis of suspension from brainiac end of the pendulum. The personality of the graph shows the physical properties of the compound pendulum. From value 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 disperse of the pendulum and its radius of gyration as obtained from the curve, the rotational inertia of the pendulum is computed. surmise: A simple pendulum consists of a small ashes called a bobsleigh (usually a sphere) given(p) to the end of a string the length of which is great compar ed with the dimensions of the bob and the mass of which is negligible in compare 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 experimentally. When the dimensions of th e suspended body are not negligible in compa! rison 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 hug of gravity is a compound pendulum. The motion of such a body is an angular vibration about the axis of suspension. The spirit for the period of a compound pendulum may be...If you want to retrieve a expert essay, order it on our website: OrderCustomPaper.com
