HW: $4-2-8$

Determine the maximum bending stress in the rebar $($steel$)$ and in the concrete. Each rebar has a diameter of $1$ in$.$ Assume the concrete carries no tension. Hint: Finding the centroid can be very ticky so you may want to rewatch video $4-25.$

$E_{\text{s}\text{t}\text{e}\text{e}\text{l}}=30,{000}^{\text{k}\text{s}\text{i}},E_{\text{c}\text{o}\text{n}\text{c}\text{r}\text{e}\text{t}\text{e}}=3,{750}^{\text{k}\text{s}\text{i}}.$
