Question $89$ #$11$ :

A civil engineer is designing a reinforced concrete beam for a residential building. The beam is $4$ meters long and is subjected to a uniformly distributed load of $15$ kN$/$m$.$ The beam has a rectangular cross$-$section with a width of $0\mathrm{.}3$ meters and a depth of $0\mathrm{.}5$ meters. Calculate:

a$)$ The total load acting on the beam.

b$)$ The maximum bending moment experienced by the beam.

c$)$ The required area of steel reinforcement to resist the bending moment.
