We consider the deformation of a rod which is un der an axial load P and a distributed transverse load f ( x ). The rod is attached to a wall at the points ( x = ,y = 0) and ( x = 1 ,y = 0) using friction free joints, so that the moments at the end points are zero. The deformation y ( x ) in such a situation is (approximately) given by the di ff erential equa tion P f(x) P y x d 2 y ( x ) dx 2 = f ( x ) x (1 x ) + py, with p defined as p = P/EI , where E is the elastic modulus of the rod, and I the moment of inertia of its cross section. For the following we will assume that things have been normalized in such a way that we end up with a nondimensional form of the equation that reads d 2 y ( x ) dx 2 = x (1 x ) 1 4 x 1 2 2 ! y. a. What are the boundary conditions for this problem? b. Plot the load f ( x ) as a function of x ....
