Unformatted text preview: FSAE Torsion Test Alex Hyatt ME222 Lab Submitted to: Adam Greer November 26, 2007 This report presents the analysis of the data and results of the torsion testing for your FSAE chassis that was brought to our facility. The torsional stiffness of the chassis with and without the engine bay cross brace was determined as was requested. In addition, a summary of the testing procedure, documentation of the data for your chassis, and additional comments about your chassis are given. Apparatus and Procedure A picture of the chassis before it is to be tested is below. Figure 1: A picture of the chassis in the fixture (taken from the Clemson blackboard webpage) The force of the load was applied only on the front left part of the chassis. The front left experienced the most amount of torsion by far, then the next highest was the right rear. This shows that the force was only causing a slight rotation or torsion and no translation. As far as the data goes, the measured values for the changes in the dial gauges were used to find the change in angle of each bar and the load cell indicates the weight shift across the front of the car and thus can be used to calculate the torue on the chassis....
