Homework Help: Dirac delta function (DE problem) solved

  1. May 23, 2005 #1
    NOTE: I actually found the correct answer while I was typing this :rolleyes: and since I already had it typed, I figured i would post anyway. mods you can do with it as you please or leave it for reference. thanks

    Here's the problem:

    A uniform beam of length L carries a concentrated load [tex]w_{0}[/tex] at [tex]x=\frac{1}2{L}[/tex]. The beam is embedded at its left end and is free at its right end. Use the Laplace transform to determine the deflection y(x) from [tex]EI\frac{d^4y}{dx^4}=w_{0}\delta(x-\frac{L}2)[/tex] where [tex]y(0)=0, y'(0)=0, y''(L)=0, y'''(L)=0[/tex].

    Here is what I did: let [tex]y''(0)=c_{1}, y'''(0)=c_{2}[/tex]
