A rectangular reinforced concrete beam carries service loads on a span of 20 ft as shown. The dead load does not include the self-weight. Use an initial beam size of 15 in. x 24 in. Design the beam for bending and show it in a sketch. Use a 75 ksi yield strength steel and 4 ksi concrete strength.

I saw this question solved before, both on Chegg and Bartleby and it was WRONG! Please,if you do not know how to solve DO NOT COPY the wrong solution.Thank you!

A reinforced concrete cantilever beam is shown below. The beam cross section is a rectangle, 12 inches deep by 18 inches wide. Material properties are: - Concrete weight: wt = 150 pcf - Concrete compressive strength: f'c = 4000 psi - Concrete tensile strength: f't = 400 psi - Steel tensile strength: fy = 60 ksi - Stirrup consists of #4 bar - Beam is not exposed to weather or in contact with soil. Determine if the beam will crack under its own weight, if its self-weight is 250lb/ft. 10 ft -18" BEAM SECTION beam will crack beam will not crack unknown, not enough information to calculate

using the table below, answer the question
