There Is a Continuous Beam with loads and cross$-$sectional sizez as shown above. When the value E $($Young$\text{'}$s modulus or modulus of elasticity$)$ is a constant of the cross$-$section beam and I is the value of the moment of inertia of the cross section of the beam, then determine and calculate:

a$.$ Global stiffness matrix

b$.$ Unknow displacement and support reaction

c$.$ Internal forces of the beam

d$.$ Field BMD $($BendingMoment Diagram$),$ SFD $($Shear Force Diagram$)$ and NFD $($Normal Force Diagram$)$

Know Quantities:

P$1=750$kg $(2$ meter$),$ P$2=1500$ kg $(4$ meter$),$ P$3=1000$ kg $(10$ meter$),$ P$4=750kg45$ degree$(12$ Meter$),P5=1500kg,Q=250k\frac{g}{m^{\text{'}}},0\mathrm{.}6$mBcA$(A)meter(B)$ meter $0\mathrm{.}3$ m
