Question:

A beam has unit length ℓ = 1 and constant bending stiffness clx) = 1. Explain the physical configuration that each of the following inhomogeneous boundary' conditions represents, and then, if possible find the equilibrium solution, assuming no external forcing;
(a) u(0) = 0. u (0) =0.m(1) = 1, w(l) = 0
(b) u(0) = - 1, u(0) = 0. u(1) = 0. u'(1) = 2
(c) u(0) = 0.u (0) = 1. w(l) = 1. w(1) = 0
(d) i(0) = 2. w(0) = 0, u(1) = -2. w'(1) = 0
