I = 160.0 cm or 1.610 m. We can now calculate the deflection the bench's seat will experience due to a point load at its center: = P L / (48 E I) However, by inspecting our formulas, we can also say that the beam's length also directly affects the deflection of the beam. | Contact, Home Rectangular Plate Calculator (deflection & stress) Unlike a disc ( circular plate ), where stresses and deflections are generally predictable owing to constant edge support, in a sheet (rectangular plate) - where edge supports vary - they are much less predictable. SkyCiv Free Beam Calculator generates the Reactions, Shear Force Diagrams (SFD), Bending Moment Diagrams (BMD), deflection, and stress of a cantilever beam or simply supported beam. Loads, on the other hand, affect the beam's deflection in two ways: the direction of the deflection and the magnitude of the deflection. An interactive drawing area allows you to design complex, multi-span beams in minutes. The bending moment can be positive, negative, or zero depending on the direction and magnitude of the load and the location of the point of application. Figure 2.2. RA + RB = 50 kN, Mz = 0 However, these formulas can only solve simple loads and a combination of these loads. The modulus of elasticity depends on the beam's material. Bending Moment Diagrams can be quickly and easily generated using the above calculator.

Deflection for simply supported beam can be calculated by the equation below: = 5wL 4 /384EI. 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. A method is for efficiently determining a very large number of terms in the series. The moment of inertia values we obtained tell us that the beam is harder to bend with a vertical load and easier to bend if subjected to a horizontal lateral load.
