The rectangular R$/$C beam shown is singly$-$reinforced with one layer of tension steel reinforcement. The concrete compressive strength is $5\mathrm{.}0$ ksi and the steel yield stress is $60$ ksi.

a$)$ Determine the cracked moment of inertia

b$)$ Determine the uncracked moment of inertia:

i$.$ neglecting tension steel

ii$.$ accounting for tension steel

Determine the cracked moment of inertia of the section shown below. Use concrete compressive strength of $4$ ksi and steel yield of $60$ ksi
