Krit University Example 2.2: (a) If the T-beam shown is uncracked, calculate the stress in the concrete
at the top and bottom extreme fibers under a positive bending moment of 112 kN. m.
(b) If f. - 20.7 MPa and normal weight concrete is used, what is the maximum
uniformly distributed load the beam can carry if it is used as a simple beam with 7 m
span without exceeding the modulus of rupture of the concrete?
(c) Repeat part (b) if the beam is inverted,
