The beam has t$-$beam cross section and is subjected to a distributed load show. a$)$ use an appropriate free body diagram to determine the reactional loads at the supports

c$)$ Use method of sections to draw a FBD between $3$m greater than or equal to x greater than $6$ and express theinternal shear and moment in terms of x

d$)$ use the shear and moment functions in b$)$ and c$)$ here above to draw the shear and moment diagrams

e$)$ from the shear and bending moment diagram drawn here above, determine the absolute maximum internal shear and absolute maximum bending moment

f$)$ locate the neutral axis of the T$-$beams cross section taking the reference axis to be lcoated at the bottom surface

g$)$ determine the moment of inertia of the t$-$beam cross section

h$)$ determine the maximum shear stress in the t$-$beam at the critical sectin where the internal shear force is maximum $($shade the area on the T$-$beam responsible for the maximum shear stress$)$
