The writer just needs to follow the file attached perfectly and develop his final output.
And, it should be like Review of literature for chassis design and Review of literature for steering design.
But for the source of literature both the design can be in a single paragraph.
Discussion paragraph can be shortened. Project Methodology should contain more info in it.
I have mentioned there review of literature chassis design instead do it as review of literature for chassis design of an NTV which has width of 1.5 meters and seating capacity of 2. And review of literature steering design instead do it as review of literature for steering design.
For steering design I also wanted to add why we are using particular type of steering. Reasoning for this question.
