A Mechanical Engineer designs machine elements that are safe, durable and economical. Since machine elements are subjected to tensile, compressive, shear or combination of these loads, hence it is essential to analyze the element under these loads for safe design. It has been seen that strength of the bar is affected by change in cross-section, notch, surface roughness etc. The notch effect increases stress in an area of a component near a crack, or a change in section, such as a sharp angle. When a body has stress concentration in it, the chances of its failure increases. These days number of...
