Beam deflection for solid rectangular beams
Calculate beam deflection for solid rectangular beams with our easy-to-use calculator. Get accurate results quickly and easily.
Measuring the deformation of a beam under load is done by calculating the deflection of the beam before and after the load is applied. The amount of deflection a beam experiences is determined by its length, cross-sectional area and shape, the material it is made of, the location of the force that causes the deflection, and the way the beam is supported. This online beam deflection calculator can be used to find the deflection of a solid rectangular beam based on the load applied to the free end and the support at the fixed end. Simply enter the width, height, length and force to compute the deflection.
MI_{Solid Rectangular Beam} = \frac{(Height^3 \cdot Width)}{12}
Deflection = \frac{(Length^3 \cdot Force)}{(3 \cdot E \cdot MI)}
Bending Stress = \frac{(Force \cdot Length)}{\frac{MI}{(0.5 \cdot Height)}}
Where:
- MI = Moment of Inertia
- E = Modulus of Elasticity in psi
