Homework Statement
A cantilever beam has uniform load w over a length of L as described by the eq.
EI y'''' = -w y(0) = y'(0) = 0 y''(L) = y'''(L) = 0
EI are constants
find y(x)
Homework Equations
L[y^4] = S^4*Y(s) - S^3*Y(0) - S^2*Y'(0) - s*Y''(0) - Y'''(0)
The Attempt at a Solution
We really didn't do anything similar to this at all in class. All I could think of doing was simply take the transformation of the equation, and we can see that two fo the terms will go to zero, but we are still left with
S^4*Y(s) - s*Y''(0) - Y'''(0) = -w/S
From here what can we really do? I don't see how we can use the boundary conditions because we have Y''(0) not Y''(L) and i don't see how we would ever get to a point that we could use that.
