Compund Pendulum

OBJECT: To study the properties of a compound pendulum, and to determine the quickening 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 length and the plosive consonant about each bloc is observed. A graph is plotted of the period versus the infinite of the axis of suspension from wiz end of the pendulum. The personality of the graph shows the physical properties of the compound pendulum. From values of the period and the be length of the equivalent simple pendulum as determined from the graph, the acceleration due to gravity is calculated. From the good deal of the pendulum and its radius of gyration as obtained from the curve, the rotational inertia of the pendulum is computed.
THEORY: A simple pendulum consists of a small ashes called a bobsled (usually a sphere) given to the end of a string the length of which is great compared with the dimensions of the bob and the mass of which is negligible in comparison 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 distance 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 the suspended body 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 horizontal axis so as to vibrate under the force 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 get a expert essay, order it on our website: Orderessay
