Influence Lines

The graphs that show the variation of a function at a specific point on a beam or truss due to a unit load placed at any point along the structure are known as influence lines in engineering. Some common functions that are studied with influence lines are shear, moment, and deflection. In designing beams and trusses, it is important to use influence lines in structures where loads would move along their span such as bridges, crane rails, conveyor belts, floor girders, etc. The influence lines help to study where a load will create the maximum effect for any of the functions.

Question

A simply supported beam is 10m long. It has an overhang of 2m at the right end.
A highway load comprising of a single point load of 150kN and a uniform load of 80 kN/m passes
over the beam. Based on the influence line for maximum bending moment at the midspan,
calculate for the magnitude of the maximum absolute bending moment produced on the beam, in
kN-m. No need to input the sign and units. Just the numerical value of your answer to the nearest
whole number.
