It's often helpful to look at a simple example. The Euler-Bernoulli equation describes a Engineering Calculators For instance, as a steel beam calculator the user would enter in a Young's Modulus of about 200,000 MPa (or 29,000 ksi for imperial units). When beams carry loads too heavy for them, they start to bend. The simplest form of this equation is as follows: The Shear Force and Moment can be expressed, respectively, as: We use these equations along with the boundary conditions and loads for our beams to derive closed-form The calculation is designed for plates that are flat, homogeneous, with the same thickness and made from one material. For a rectangular plate clamped at the edges W is subject to the boundary After that point load, you'll see that by summing the forces, the shear force ends up being negative: Plotting this, we can get the full shear force diagram: The above steel beam span calculator is a versatile structural engineering tool used to calculate the bending moment in an aluminium, wood or steel beam. & Young, Formulas for Stress and Strain, 5th eddition, page 386. Per. In engineering, it's important to understand and calculate beam deflection because it can affect the overall strength and stability of a structure. The results can be used for initial estimates - For more accurate results it is recommended that Engineering Calculators, Related: In short, you would simple move along the beam plotting the vertical force and how it changes along the member. There are available on another page on our website called Bending Moment Formula. You will generally need to start by calculating the reaction forces (shown in the above segment) before plotting the shear force diagram. Engineering Calculators Menu Engineering Analysis Menu. How do you select plate thickness? small concentric circle of ro, qo (N/mm, Uniform The . Flat Plate Stress Calcs = 0.175966540277 MPa The diving board is the beam and your weight is the load that's causing it to bend. Input your beam length using the 'Beam' menu. Manufacturing Processes For a simply supported plate the deflection must satisfy the following boundary conditions on the plate boundary (6.82a) (6.82b) where is the bending moment in the direction normal to the boundary and denotes the tangential to the boundary direction. The plate is flat, of uniform thickness, and of homogeneous isotropic material; the thickness is not more than about one quarterof the least transverse dimension, and the maximum deflection, all forces, loads and reactions are normal to the plane of the plate; and, the plate is nowhere stressed beyond the elastic limit. Hydraulics Pneumatics 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. StructX has adopted this way of drawing bending moments throughout.
