Question

solve with engineers theory of bending a three-point bending test on a simply supported, straight beam made of structural steel (modulus of elasticity E=210GPa, Poisson’s ratio ν=0.3), with dimensions 10000mm long, 2000mm wide, and 500mm thick, subjected to an external load of 7000N plus the beam's weight? The beam is required to meet a stress constraint of 140MPa and a deflection constraint of L/1000, where L is the span of the beam.
