For the frame shown below, assume support A to be roller and support D to be pinned.

a$.$ The support reactions at A and D $(2\mathrm{.}5$ points$)$

b$.$ Draw the shear force diagram $($SFD$)(5$ points$)$

c$.$ Draw the bending moment diagram $($BMD$)(5$ points$)$

d$.$ Specify the location of any point, if any, where the shear force is zero $(2\mathrm{.}5$ points$)$

e$.$ Specify the location of the point of inflection, if any. $(2\mathrm{.}5$ points$)$

f$.$ Locate the point$/$region of the maximum shear and maximum bending moment and mention their values. $(2\mathrm{.}5$ points$)$
