Steven Akdemir Prof. Yan Liu Alexander Puchalski, Antonio Nigro, Bassam Hinnawi, Matthew Jeffers Lab 127 April 12, 2016 Torque and Rotational Inertia Introduction: We performed this lab with two main objectives in mind: to experimentally determine the rotational inertia of a rotating body by measuring its angular acceleration and applying the relation: Σ τ = , and to practice computation of rotational inertias for objects with different shapes/mass distributions. Procedure: Before performing the lab, we gathered together the following materials: a computer with Capstone software installed. 850 Universal interface, a rotational system (which included a base, a photo-gate sensor, a step pulley w/ string, and a pulley on a rod), a Rotational disk with diameter 25.4 cm, a ring with outside diameter 12.7 cm, a 50 g mass hanger, 200 g weight, bubble level, a Vernier caliper, and a digital scale for recording mass. We set up the rotational system as shown in page 54 of the lab manual, and the computer was already connected to the 850 interface when we came to the lab. We then plugged the connector from the photo- gate into the Digital Inputs Port 1 on the interface, and opened the file “Lab 127 Torque and Rotational Inertia for 111A” on the computer. Part 1: Theoretically Determine Rotational Inertia of Disk and Ring 1. Measure the masses of the disk and the ring 2. Measure the radius of the disk, as well as the inner and outer radii of the ring

### 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.
