About the Beam Deflection Simulator

The Beam Deflection Simulator is a simple tool for analysing how a beam behaves when different loads are applied to it. It can be used to study both cantilever and simply supported beams and to see how the selected material, cross-section, beam length and applied loads affect the calculation.

To use the simulator, first select the beam type and enter the beam length. Then select the material and provide its Young's modulus and yield strength. The cross-section of the beam can also be selected from the available shapes, and the required dimensions can then be entered. The simulator uses these dimensions to determine the second moment of area of the section.

Loads can be added individually to the beam. The available load types are point loads, uniformly distributed loads (UDL) and applied moments. For a point load, the load magnitude and its position along the beam are entered. For a UDL, the load intensity and the starting and ending positions are specified. For an applied moment, the moment magnitude, position and direction can be selected.

The calculations are based on the applied loads and the support conditions of the selected beam. Support reactions are determined using the equilibrium conditions of the beam, including the effects of point loads, distributed loads and applied moments. The loading information is then used to determine the internal forces and bending behaviour of the beam.

The simulator also calculates the second moment of area of the selected cross-section, which is an important section property used in beam bending and deflection calculations. The value depends on the geometry and dimensions entered for the selected section.

Enter the dimensions and loads in the units shown beside each input. Make sure that the values represent the actual beam and loading conditions you want to analyse. The calculator is intended for engineering calculations and learning purposes and should not be used as the sole basis for the design or safety assessment of a real structure.
