Question

The beam shown in the figure below has the following properties: 28-ft simple span

f'c = 4000 psi

fr = (7.5)(square root of (f')(c))

reinforced concrete weight = 150 lb/ft3

Solve for :

1.) The cracking moment in kp-ft

2.) The self weight of the beam in kp/ft

3.) The superimposed uniform load that will cause the beam to crack in k/ft
