Mechanical engineering

is the discipline that applies engineering, physics, and materials science principles to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering disciplines.

14.5 Fabrication Cutting and forming Cutting and machining Thin material can be like steel, but more readily. For material cold-sawing is used, with either a circular or saw. Aluminium (except...
The following is a crude statement of how aluminium differs from steel as a structural material (G = good, B = bad): Light:one-third the density GNonrusting:seldom needs painting GFabrication:design your own sectionsGBrittle-fracture:generally easier GExpensive: about 3 times the cost by volumeBDeflections: E one-third that of steel BFatigue: more...
A Stirling engine is a heat engine that is operated by a cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, resulting in a net conversion of heat energy to mechanical work. More specifically, the Stirling engine...
Modern tennis balls must conform to certain criteria for size, weight, deformation, and bounce criteria to be approved for regulation play. The International Tennis Federation (ITF) defines the official diameter as 6.54–6.86 cm (2.57–2.70 inches). Balls must have masses in the range...
