The Principle of Minimum Potential Energy - YouTube
WebThe total potential energy is a new concept, and it is de ned as the sum of the drain energy and potential energy = U+ (W ) = U W (8.7) Consider for a while that the material is rigid, for which U 0. Imagine a rigid ball being displaced by an in nitesimal amount on a at ( = 0) and inclined ( 6= 0) surface, Fig. (8.3). x x "u ! "u H "H The minimum total potential energy principle is a fundamental concept used in physics and engineering. It dictates that at low temperatures a structure or body shall deform or displace to a position that (locally) minimizes the total potential energy, with the lost potential energy being converted into kinetic energy (specifically heat). WebEnergy principles in structural mechanics express the relationships between stresses, strains or deformations, displacements, material properties, and external effects in the form of energy or work done by internal and external forces. Since energy is a scalar quantity, these relationships provide convenient and alternative means for formulating the … crosco e-line
