Q$2)$ The beam shown below has an I shape cross$-$section.

$(1)(15$ points$)$ Calculate the support reaction at point A and B$.$

$(2)(15$ points$)$ Draw the shear force and bending moment diagram of the beam.

$(3)(15$ points$)$ Calculate the maximum normal bending stress on the beam and indicate where it occurs on the beam.

$(4)(15$points$)$ Calculate the maximum shear stress on the beam and indicate where it occurs on the beam.

There could be more than $1$ location with the maximum stress
