A reinforced concrete beam (300mm by 500mm) with effective depth of 440mm is 5 meters long and supports a uniform load of 15 KN/m and a concentrated load of 30 KN at the midspan of the beam.
a. find the max. moment experienced by the beam
b. find the location of the neutral axis from the bottom of the beam if it requires 6-16mm diameter bar needed for tension only. assume n=10
c. What would be the stress developed in the concrete and steel.
d. compute for the moment of inertia
