They can be determined using the principles of statics and mechanics of materials. Input your beam length using the 'Beam' menu. 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. Loads, on the other hand, affect the beam's deflection in two ways: the direction of the deflection and the magnitude of the deflection. The diagram shows the variation of the bending moment along the length of the beam and provides information about the distribution of the internal forces in the beam. The calculation is designed for plates that are flat, h. 1.Introduction. Show solution. In structural engineering, deflection is the degree to which a part of a structural element is displaced under a load (because it deforms).It may refer to an angle or a distance. I have checked my results against Roark and they seem to be OK. We equipped our beam deflection calculator with the formulas that engineers and engineering students use to quickly determine the maximum deflection a specific beam will experience due to the load it carries.
