Calculating Beam Load for One Way Slab: Analysis and Solutions

[tzx9633]

Homework Statement

In this question , i think the author is wrong . In the question , the author use 0.5nIx , i know it's for one way slab .
P/ s : Photo 701-703 is for first case . Photo 704 to 706 are for 2nd case .

Homework Equations

The Attempt at a Solution

But , i think the load from slab should be 8 x 0.5nIx , because we can see that at the first example , the load is from both the left / right of the beam ...So , the same things go to the 2nd example , there's should be load due to the 8 slab ... ( Just like i shown in photo )
