Simply supported beam natural frequency calculator to calculate natural frequency of a uniform beam with uniform load w per unit length including beam weight. Beam is simply supported from both ends. The natural frequency formula for simply supported beam is $${ f }_{ n }=\frac { { K }_{ n } }{ 2\pi } \sqrt { \frac { EIg }{ w{ l }^{ 4 } } } $$
Here in the formula, I is area moment of inertia, l is length of the shaft, E is modulus of elasticity and w is uniform load.
Note: Use dot "." as decimal separator.
