Problem I For the beam shown below:

a$)$ Find reactions at support A and support $D$

b$)$ Draw the shear diagram

c$)$ Draw the bending moment diagram

d$)$ What is the design shear V and bending moment M for the beam $($highest shear and moment values to be used in the design of the beam$)?$

e$)$ For the design shear $vv$ found in part d$),$ calculate the shear stress in the beam section

f$)$ For the maximum positive moment found in part d$),$ calculate the bending stress in the beam section.
