- Welds, machining tool marks, and stress reversals, such as those in rotating parts, can cause a progressive failure even on a lightly loaded part such as a shaft. There is no sign of ductility, only a smooth surface having striations like a clamshell. How would you identify this kind of failure? What is it called?arrow_forwardWhat precisely is stress testing, and why is it advantageous to begin with?arrow_forwardA GO/NO-GO snap gage is required to inspect the diameter of a shaft that is 1.000 ± 0.020.

- Research about friction. Include diagrams, tables, graphs and/or charts if necessary. Include all equations involved in the topic. The specific topics are enumerated below: 1. DEFINITION AND THEORY OF FRICTION 2. ANGLE OF FRICTION 3. LAWS OF FRICTIONarrow_forwarda) During sliding of a cylindrical steel pin against a steel disc in a pin-on-disc test in air, the coefficient of friction is initially around 0.7, but then falls to 0.5 as the test proceeds. At the end of the test, the wear track on the disc is rough and black in colour, with a black powder on the disc surface outside the wear track; chemical analysis of the wear track shows a high oxygen level. (b) A test identical to that described in part (a) is conducted, but this time the test is conducted in vacuum. The coefficient of friction remains high through the test, the wear volumes are much greater, and the track on the disc surface following the test is very rough and silvery in colour. (c) A test identical to that described in part (a) is conducted, but this time the test is conducted in air at 300 ◦C. At the end of the test, the wear track on the disc is very smooth (shiny) and black in colour, with no debris on the disc surface outside the weartrack; chemical analysis of the wear…arrow_forwardWhy do the supports that resist a force, such as a pin, restrict displacement?arrow_forward
