FlexBeam Pro


FlexBeam is a user-friendly calculator for beam analysis: calculate beam deflection and column buckling. Just enter the data and FlexBeam instantaneously provides you with the outcome. You can immediately see, on one window, which load is calculated, the second moment of area and the resulting stress, deflection and slope. Buckling calculations are done for central load (Euler-formula) and for eccentric load (Secant-formula). You can also try the free version first.
