Problem $2$M

Find the required reinforcement so that the beam can carry the applied load giving that the beam width $b={20}^{\text{'}\text{'}}$ and the effective depth $d={40}^{\text{'}\text{'}}$

$f_c^{\text{'}}=5,000$

$f_y=60,000$

$P_D=40$kips

$P_L=60$kips

$P_D=40$ kips

$P_L=60$ kips

${}_D=2kft($including beam weight$)$

${}_L=4kft$
