Integrated into each beam case is a calculator that can be used to determine the maximum displacements, slopes, moments, stresses, and shear forces for this beam problem. Note that the maximum stress quoted is a positive number, and corresponds to the largest stress magnitude in the beam. It does not distinguish between tension or compression (this distinction depends on which side of the beam's neutral plane your c input corresponds).
 Calculator Input
 Length of beam, L: mm cm m in ft Size of Loads on beam, P: N lbf Distance between loads and beam ends, a: cm m in ft Young's Modulus, E: Pa kPa Mpa GPa psi ksi Distance from neutral axisto extreme fibers, c: mm cm m in ft Moment of Inertia, I: mm^4 cm^4 m^4 in^4 ft^4
