Problem $1.$ Analyze the following T$-$beam cross section under bending and determine if it

behaves under tension$-$controlled. Perform the following tasks:

$($a$)$ Determine if the section behaves like a true T$-$beam.

$($b$)$ Calculate the nominal resistance of the section.

$($c$)$ Determine whether it is under tension$-$controlled or not.

$($d$)$ Check if it satisfies the minimum reinforcement requirement.
