Beams are the extended members of a structure that carry the loads brought by the horizontal slabs of the structures like solid concrete floors, wooden floor joist systems, and roofs. Show solution. Both of them inhibit any vertical movement, allowing on the other hand, free rotations around them. A bending moment diagram is an important tool for engineers because it allows them to understand the behavior of the beam under load and to design the beam to resist the loads safely and efficiently. It features only two supports, one at each end. To further understand this concept, let us consider the cross-section of a rectangular beam with a width of 20 cm and a height of 30 cm. Based on the results of calculations, the minimum critical load on adjacent edges, given by compressive stress y, corresponding to the first form of the loss of . 0 = -50 kN (-5m) + RB(-10m) + RA(0) Determine the safe concentrated live load that can be placed at midspan of the beam.
