A beam with a span of 7.0 m between supports has an overhanging extended part of 2.0 m on one side only. The beam carries a uniform dead load of 30 kN/m (including its own weight) and a uniform live load of 18 kN/m. Design the smallest singly reinforced rectangular section to be used for the entire beam. Select steel for positive and negative moments. Use f 'c = 30 MPa, fy=400 MPa, and b=300 mm). (Determine the maximum positive and maximum negative moments by placing the live load once on the span and once on the overhanging part. 7.0 m 2.0 m

A beam with a span of 7.0 m between supports has an overhanging
extended part of 2.0 m on one side only. The beam carries a uniform dead load of
30 kN/m (including its own weight) and a uniform live load of 18 kN/m. Design the
smallest singly reinforced rectangular section to be used for the entire beam.
Select steel for positive and negative moments. Use f 'c = 30 MPa, fy=400 MPa,
and b=300 mm). (Determine the maximum positive and maximum negative
moments by placing the live load once on the span and once on the overhanging
part.
