Mechanical engineering is a branch of engineering concerned with designing, producing and operating machinery, ranging from ranging from relatively simple items to more complex machinery and even entire facilities and plants.
Heat or thermal energy can be transformed into mechanical energy. By using the expansive property of gases or steam, gas or steam turbines transform the thermal energy into pressure or velocity. These are forms of mechanical energy. Elevation over a base level is another form of energy, which ...
