A 6-m simply supported parabolic beam having a width of 400 mm and height of 500 mm is reinforced with 4-32 mm placed 100 mm from the bottom of the beam. However, by inspecting our formulas, we can also say that the beam's length also directly affects the deflection of the beam. Plates have free, simply supported or fixed boundary conditions. Uniform Loading over a snall circle of radius ro remote from the edges. . Engineers can also use empirical formula to quickly calculate the deflection of a beam which is what we'll use for the below example: Lets consider a simple supported beam with a span of a uniform load of w = 10 kN/m over a L = 10m span, and the following material properties: Youngs modulus, E = 200,000 MPa, and the moment of inertia about the y axis is I = 0.0015 m^4. This means that the bench seat will sag around 2.6 millimeters from its original position when the child sits in the middle of the bench. This difference in the moment of inertia values is the reason why we see beams in this configuration wherein their height is greater than their width. Math can be difficult, but with a little practice, it can be easy! Materials and Specifications Rectangular Flat Plate , uniform load ,edge clamped.
