For a concrete section with b=14", d=18.5", 4#7 bars with 2.5" cover, calculate: 1- The cracking moment, Mcr ,in ft-kips, using normal weight concrete with f'c=4000 psi and fy%360,000 psi. 2- If the total applied service load (including beam weight) w=1 k/ft, and the beam is simply supported with a span of 15 ft, is the beam going to crack under the applied loading? Explain.
