Problem Statement

This device will measure the torsional stiffness of a FSAE race car frame. Our design will apply a torsional load to the frame while simultaneously providing precise measurements required to calculate the applied load, displacement, angular deflection, and torsional stiffness. Unlike the most popular method of testing torsional stiffness by applying load with a lever, our device twists the frame using hydraulic bottle jacks with an integrated pressure gauge. This aspect enables precise control of the twist, and the pressure gauges provide the capability of load-measurement. The validity of measurements will be assessed by comparing results to theoretical calculations.
