To study the variation of T with l for a compound pendulum (Bar pendulum) and then to determine (i) the value of acceleration due to gravity (g) in the laboratory, (ii) position of centre of gravity of the bar, and (il) the radius of gyration (K) of the bar about an axis passing through C.G. and perpendicular to its length
The Bar Pendulum Apparatus, also known as a Compound Pendulum, is a physics laboratory instrument designed to study the variation of the time period (T) with the effective length (l) of a compound pendulum. It is used to determine the acceleration due to gravity (g) in the laboratory, locate the centre of gravity of the bar, and calculate its radius of gyration (K).
The apparatus consists of a rigid metal bar with multiple holes or suspension points, allowing the bar to oscillate about different horizontal axes. By measuring the time period of oscillations at various suspension points, students can analyze the relationship between time period and length and perform calculations based on the principles of simple harmonic motion and rotational dynamics.
Ideal for physics practical laboratories in schools, colleges, universities, and engineering institutions, the Bar Pendulum Apparatus provides a hands-on learning experience for experiments involving gravity, oscillations, and the physical properties of rigid bodies.
Aim : Study the stated oscillatory system and determine the relevant period, frequency, coupling or mechanical parameter.
