Question:
A one-dimensional problem of a prismatic bar (see the following figure) loaded under its own weight can be modeled by the stress field σx = σx(x), σy = σz = τ xy = τ yz = τ zx = 0, with body forces Fx = ρg, Fy = Fz = 0, where r is the mass density and g are the local acceleration of gravity. Using the equilibrium equations, show that the nonzero stress will be given by σx = ρg(l – x), where l is the length of the bar.
