A 12m simply supported beam is cambered up by a compressive force acting on its cross-section. The compressive force has a magnitude of 1200kN and is acting at a constant eccentricity of 150mm below the centroid. The beam has a width of 450mm and depth of 600mm and carries a total uniform load of 10kN/m distributed throughout the span. If a downward concentrated load should be added at the midspan so that the beam will be leveled horizontally, determine the magnitude of the concentrated load. Use modulus of elasticity of the material E=30GPa.

I need right solution 

A 12m simply supported beam is cambered up by a compressive force acting on its cross-section.
The compressive force has a magnitude of 1200kN and is acting at a constant eccentricity of
150mm below the centroid. The beam has a width of 450mm and depth of 600mm and carries a total
uniform load of 10kN/m distributed throughout the span. If a downward concentrated load should be
added at the midspan so that the beam will be leveled horizontally, determine the magnitude of the
concentrated load. Use modulus of elasticity of the material E=30GPa.
