Met 314 Torque Measurement, Jose Bejar
All Undergraduate Projects
As part of the Mechanical Engineering Technology program, students are required to take a Thermodynamics class. In this class one of the labs they do consists of an air motor running a water pump. The professor teaching that class wanted a device that would fit within the lab rig which would calculate the torque produced by the motor. Therefore this project consists of building a device that will allow the case (body) of the air motor to fully rotate opposite to the rotation of the shaft in order to measure the torque the motor produces at certain revolutions per minute. …

Resonance Frequencies Of A Spherical Aluminum Shell Subject To Static Internal Pressure, Andrew A. Piacsek, Sami Abdul-Wahid, Robert Taylor
All Faculty Scholarship for the College of the Sciences
Measurements of the vibrational response of a spherical aluminum shell subject to changes in the interior pressure clearly demonstrate that resonance frequencies shift higher as the pressure is increased. The frequency shift appears to be smaller for longitudinal modes than for bending wave modes. The magnitude of frequency shift is comparable to analytical predictions made for thin cylindrical shells. Changes in the amplitudes of resonance peaks are also observed. A possible application of this result is a method for noninvasively monitoring pressure changes inside sealed containers, including intracranial pressure in humans.
