Hi,

how can I solve a system of ordinary differential equation (with relative boundary condition) in mathcad 15?

I must determined an elastic linear equation for a beam fixed to an extremity and with to transverse force applied in different point.

I suppose that E and Jx are constants, and you know M(x)...?

I Luc,

yes are constant. E is young Modulus and Jx is moment of inertia.

Thanks Fred,

and how can I obtain the graph of rotation of sections dy(x)/dx? I try to differentiate the expression but I obtain a wrong distributionCattura.PNG

Right-click on Odesolve(x,Len), and choose "fixed" instead of "Adams/BDF", then:

Quirks of numeric solvers!
