Q$1/$ The trusses shown in Figures $(1-7)$ are used to cover an area of a warehouse which consists of two trusses, the first one at the beginning of the warehouse and the second at the end of the warehouse, the cover is corrugated metallic sheets. Neglect the effect of wind load. By using the given data, it is required to:

i$.$ Calculate the forces in all members of the truss.

$[20$ Marks$]$

ii$.$ Design all tension members.
