Structural Beam Deflection, Stress, Bending Equations and calculator for a Beam Supported on Both Ends with Uniform Loading Stress and Deflection equations and calculator.

Beams of Uniform Cross Section, Loaded Transversely

Total Load ("W")

or

Line Pressure Load (p)

**Beam Deflection, Stress Uniform Loading Calculator**

Stress at any point

Stress at center of constant cross section

Deflection at Any Given Point

Maximum deflection at Center

With Total load "W"

or

Maximum deflection at Center

With Line Pressure Load "p"

Where:

E = | Modulus of Elasticity | psi |
(N/mm |

I = | Moment of Inertia | in^{4} |
(mm^{4)} |

= | Length of Beam | inches | (mm) |

W = | Total Load on Beam | lbs | (N) |

p = | With Line Pressure Load | psi-in | (N/mm) |

s = | Stress at the cross-section being evaluated | Lbs/in^{2} |
(N/mm^{2)} |

y = | Deflection | inches | (mm) |

x = | Some distance as indicated | inches | (mm) |

Z = | section modulus of the cross-section of the beam = I/z | in^{3} |
(mm^{3)} |

z => | distance from neutral axis to extreme fiber (edge) | inches | (mm) |

- Please note letter "" (lower case "L") is different than "I" (Moment of Inertia).
- Deflections apply only to constant cross sections along entire length.
