A deflection curve is:
EIy''''=w
E, w, and I are constants.
The downward direction is considered positive.
I have these initial conditions (the beam is fixed at 0 and L):
y(0) = 0
y(L) = 0
y''(0) = 0
y''(L) = 0
I have to find a solution for these conditions and also find the max deflection in the y direction.
I believe I found the solution for y, but I have some constants that I am unable to define, so I am not sure how (or if) I can find the maximum deflection.
I came up with y = (wx^4)/24EI + Ax^3/6 + Bx (A and B are yet to be defined constants)
To find the maximum deflection, I assume I should set y' equal to zero to find the maximum, which gave:
0 = (wx^3)/6EI + (Ax^2)/2 + B
Is there something more I can do to find the maximum deflection?
Thanks
