ABSTRACT This experiment was conducted to determine the mass moment of inertia at the centre of gravity, I G and at the suspension points, I O1 and I O2 by means oscillation. The finding differs between the values of I O and I G obtained from the experiment and from the theoretical value. The potential factors that caused the difference in values are further discussed. The finding was that the wooden pendulum oscillates in non-uniform motion especially when it was suspended at I O2 .Based on the result, it can be concluded that the value of I G and I O from both suspension points were different although they share the same value of mass. The period was also different for both setting points. After the data was taken, the period of oscillation, T 1 and T 2 were obtained from the two different suspension points. Hence, only after obtaining the value for T value, the value of I G and I O can be calculated. The errors that occurred might be due to the disturbance caused by surrounding and human error. The time for 10 oscillations was taken manually by using stopwatch. By the end of this experiment, the values of I G and I O were able to be calculated using formula and were compared with the theoretical value.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
