It is a structural element used in building construction when a beam stronger than an all-wood beam is required, but the strength of an all-steel beam isn't needed. The distance from the lens to the point where the beams cross is the focal length of the lens. The moment is calculated using the formula M=wL^2/8 for uniformly loaded beam, where L is the unsupported length of the beam and w is the load applied. The moment along the length of the beam is found by calculating the area of the shear diagram. The slope of the beam at support j is tanθ j. Purchase the game from: Steam. To solve indeterminate systems, we must combine the concept of equilibrium with compatibility. I=10*10^6 and E=0. Simply Supported Beam Distributed Load Formulas:.
