Beam deflection derivation

  1. Jun 19, 2008 #1
    1. The problem statement, all variables and given/known data
    hi i am currently trying to mathcamatically derive the beam deflection formula for a double cantilever simple beam. i have the beam deflection formula y= (FL^3)/(48—Iε) as well as M ymax / I as well as 1/p = M/EI but am not sure how to link them together. any help will be apprecieated
    Thanx :)

    See my questions noted in red. Are you looking for the derivation of the beam deflection formula [tex] d^2y/dx^2 = M/EI [/tex] ? You might want to google it.

    you definitely need to consier the two beams as springs in parallel or series, then get the effective spring constant
