Deflection Lite is the most interactive, fast, and precise app available for structural beam analysis. Simply drag loads and supports on the beam, and see how it bends. RESULTS Calculate reactions, shear force, bending moment, and beam deflection quickly and easily. CROSS SECTION DATABASES Specify elastic modulus and moment of inertia values directly, or find common shapes and materials using the built-in databases, which include most international steel sections, as well as some aluminum and wood shapes. UNLIMITED LOADS AND SUPPORTS Simply drag any load or support on the beam. • Concentrated point loads • Distributed loads • Moment loads • Simple supports • Fixed supports • Fixed hinges • Floating Gerber hinges OTHER FEATURES • Export your design to a permalink that you can share. • Automatic detection of local maxima and minima in diagrams • Metric and standard measurement units CONTACT We like to hear from you!
