4th order differential equation

Hello, Can anyone help me with solving below?

EI(d^4v/dx^4) = w

Boundary conditions are

v(x=0) = 0 ; v(x=L)= 0; dv/dx(x=0) = 0 ; dv/dx(x=L) = 0

whats EI? upload the question in latex form

[Stephan]

EI usually represents the stiffness matrix

Answer 1

[madhan ravi]

syms y(x) w EI L

c1=y(0)==0
y1 = diff(y,x)
c2=y1(0)==0 
c3=y(L)==0
c4=y1(L)==0

y(x)=dsolve(diff(y,x,4)==w/EI,c1,c2,c3,c4)

Thank you so much.

[madhan ravi]

Anytime :)

Answer 2

[Ahmed Al Jasar]

 y''''=w/EI, y(0)=0, y'(0)=0 ,y(L)=0, y'(L)=0
I am trying to find a deflection in a beam y(x), which is dependent on the load(w) and the stiffness (EI), E and I are constant so I guess I need to do all of them symbolic!
