For the beam and loading shown below, determine the deflection and slope at B and the reaction force

and moment at $A,$ using three $2-$node beam elements $($of equal length$)$ for section $AB$ and four $2-$node

beam elements $($of equal length$)$ for section $BC.$

Given: Elastic modulus $E=205$GPa; Poisson's ratio $v=0\mathrm{.}3$; distributed loading $w=12k\frac{N}{m},L=6\mathrm{.}4$

m ; moment of inertia $I_z=24\mathrm{.}8{10}^{6}m{m}^4.$ Take cross section area with diameter $100$ mm
