2. Press the ‘Peak Hold’ button of the Load Meter so that it records the maximum torque in the test. 3. For the first part of the test the specimen will be stressed in its elastic region, so you must increase the angle of twist in small steps of 1 degree. 4. At each angle, record the angle and torque value. 5.ME 354 LAB #4: DISCUSSION OF THE TORSION TEST Each lab section performed a torsion test of a cylindrical 6061-T6 aluminum specimen.

Report Torsion Test - Free download as Word Doc (.doc / .docx), PDF File (.pdf), Text File (.txt) or read online for free. The document describes an experiment to test the torsion properties of steel, cast iron, aluminum, and copper specimens. The specimens were subjected to torsion testing using a torsion machine to measure torque and angle of twist. Scrotal complaints are relatively common in the emergency department, comprising at least 0.5% of all emergency department visits. Testicular torsion is a time-dependent diagnosis, a true urologic emergency, and early evaluation can assist in urologic intervention to prevent testicular loss. Ultrasound is the ideal imaging modality to evaluate the . The test configuration depicted in Figure 3includes a test source on one end (which generates the light signal), and a test meter on the opposite end (which receives the light signal). In addition, it is interesting to note that two test jumpers are included in this configuration despite it being referred to as a “Onejumper End- -to-end Test”.11/9/2011 3 Test Device Aluminum Brass Copper Test Procedure • Set up the test device and clamp the first specimen based on the instruction • Put 10N weight as counterweight. • St ti f th l f l th di l Starting from the angle of zero, place the dial gauge diametrically opposite of the load weight and set to zero.
