Physical interpretation of Neumann-Dirichlet conditions

[QUOTE="A.Magnus, post: 4985880, member: 531393"] I am working on a PDE problem like this: Consider the wave equation with homogeneous Neumann-Dirichlet boundary conditions: [CENTER]##\begin{align} u_{tt} &= c^2U_{xx}, &&0<x<\mathscr l, t > 0\\ u_x(0, t) &=u(\mathscr l, t) = 0, &&t > 0\\ u(x, 0) &=f(x), &&0<x< \mathscr l\\ u_t(x, 0) &=g(x), &&0<x< \mathscr l \end{align}## [/CENTER] (a) Give a physical interpretation for each line in the problem above. (b) State the eigenvalue problem for ... (c) ... (d) ... I am posting this asking for help on answering (a) since I do not have background whatsoever in either engineering or physics. I know how to work out the rest of questions after (a), since they are all math questions. Thank you very much for your time and help. [/QUOTE]
