The Science Club of MBU conducted a technical event on 4th April, 2025 from 10:00 AM to 12:00 PM in the Physics Lab. The experiment involved estimating the acceleration due to gravity (g) using both a compound and a simple pendulum.
This event ran smoothly under the supervision of faculty coordinators Dr. Naga Malleswari from the Physics Department, SOLAS. Forty B.Tech II Semester CSE (AIML) students participated in the experiment. The compound pendulum experiment was conducted using a rigid body that oscillates about a fixed horizontal axis. The setup included a stopwatch, meter scale, and knife-edge pivot. Students measured the distance from the pivot to the center of gravity (h) and recorded the period (T) for small-amplitude oscillations. Varying the pivot position allowed them to determine different values of h and T, which were then used in the formula to estimate g.
In the simple experiment, students suspended a metallic bob from a fixed point using an inextensible string. By measuring the length (l) and recording the period (T) for ten oscillations, they minimized errors. A graph of T² versus l was plotted, and the slope was used to calculate g using the equation g=4π²(1/T²).
The event proved to be an inspiring and engaging session, igniting creativity and problem solving skills among students. It also raised awareness and interest in innovative thinking. The event organizers sincerely expressed their gratitude to all the participants for their invaluable support and contributions for making the event a remarkable success.
