Mechanical energy nonconservative forces, like frictional forces, will be present, but often they are of negligible values and the mechanical energy's being constant can therefore be a useful approximation. In elastic collisions, the mechanical energy is conserved but in inelastic collisions, some mechanical energy is converted into heat. The equivalence between lost mechanical energy (dissipation) and an increase in temperature was discovered by James Prescott Joule. Many devices are used to convert mechanical energy to or from other forms of energy, e.g. an electric motor converts electrical energy to mechanical energy, an electric generator converts mechanical energy into electrical energy and a
Bank of Dalian Bank of Dalian Bank of Dalian Co., Ltd. is a Chinese urban commercial bank, with its headquarters in Dalian, Liaoning Province, China. In 1998, it was established as Dalian City Commercial Bank and opened its branches only in Dalian. In 2007, it changed its name to Bank of Dalian and has since opened branches in Tianjin, Beijing, Shanghai and five other cities in China. In 2015, China Orient Asset Management subscribed the new shares of the bank, as well as bought some assets from it. The assets itself were originally a collateral. In 2016 the bank signed a strategic agreement
