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 prime X c)

reinforced concrete weight = 150 lb/ft3

Solve for :

1.) The total area of the section in in2

2.) The gross moment of inertia in in4

3.) The cracking moment in kp-ft

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

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