    Need to calculate beam deflection under gravity using theoritical formula

    Eesh D

      Hi all,

       

      WRT below image the length of the beam is 20" and the beam section is a square of side 1". The beam is subjected to gravitational load only.

      Material used is Plain carbon steel of E=30457924.91 psi, Density=0.281793 ib^in3 and Mass= 5.64 pounds.

      From SW simulation I'm getting a maximum deflection of 0.002 in (both solid and beam elements).

      In SolidWorks SImulation tutorials the formula given to calculate the maximum deflection under gravitation load is UY = ( 3 * w * L4) / (24 * E * I ).

      Unfortunately I'm not getting the same results using the theoretical approach.

       

      Please help me what values I should consider in the formula so that I can achieve the goal?

       

      Thanks and Regards,
