BAR PENDULUM - ACCELERATION DUE TO GRAVITY
Product Description
Experiments: To study the variation of T with L for a compound pendulum (bar pendulum) and then to determine
(I) the value of the acceleration due to gravity (g) in the laboratory ,
(ii) the position of centre of gravity of the bar,
(iii) The radius of gyration K of the bar about an axis passing through C.G. and perpendicular to its length.
The bar pendulum consists of a metallic bar of about one meter long. Aseries of circular holes each of approximately 5 mm in diameter are made along the length of the bar. The bar is suspended from a horizontal knife-edge passing through any of the holes (Fig. 2). The knife edge, in turn, is fixed in a platform provided with the screws. By adjusting the rear screw the platform can be made horizontal.
A bar pendulum is the simplest form of compound pendulum. It is in the form of a rectangular bar (with its length much larger than the breadth and the thickness) with holes (for fixing the knife edges) drilled along its length at equal separation.
