Develop a finite element model to solve the displacement and stress at different points. Assume that you have $2$

elements, the first one is from $0$ to $12$ inches and the second one is from $12$ to $24$ inches. Thickness is $1$ inches,

$E=30({10}^6)$ Psi, and $=0\mathrm{.}2836l\frac{b}{i}{n}^3$

Point: In this case, as we have density $(),$ so we have a

body force related to weight. It is inside the structure

and is in the positive $x$ direction $($downward$).$ This body

force can find by density time cross section area

$A.$
