Problem $($I keep sending because of questions $7-10$ are not answered, thank you$)$

A $9m$ long simply supported steel beam $)$ supports a $7\frac{kN}{m}$ uniformly

distributed load and two equally spaced $5kN$ point loads as shown below. The cross section of

the beam has been built$-$up from three plates as shown in the section drawing.

Calculate the following for this beam:

Cross Section Properties

Location of the Neutral Axis $($N$.$A$.)$

Moment of Inertia $($I$)$ about the Neutral Axis

Elastic Section Modulus $($S$)$
