Experiment: Mechanical Testing- Impact & Hardness Testing

A fundamental study on the flow past a circular cylinder ...

Flow patterns generated around a circular cylinder immersed in a uniform flow are shown in Figure 1 (Hughes & Brighton, 1999). In relation to the flow around an object, a combination of a uniform flow with a circular cylinder will be the simplest case. The pattern of this flow varies depending upon the Reynolds number.

Experiment: Heat Treatment - Quenching & Tempering

specimens after cleaning one of the surfaces with sand paper to remove any hard carbon deposits that may have formed on the surface. Take 5 readings on each sample. b. Determine the Charpy impact strengths of all the heat treated specimens (make sure the Impact Testing Machine is rezeroed after each test!).

over the land’s surface. Roughness is determined by both topography and vegetation. Wind also blows dust from the surface into the atmosphere, which interacts with the atmospheric radiation. The marine and terrestrial biospheres have a major impact on the atmosphere’s composition. The biota influence the uptake and release of greenhouse gases.
