Answer 1

Correct Answer - Option 2 : one fourth

Roof Trusses:

• They are economical for spans more than 6 m.
• The pitch of a roof truss (Rise/Span) should be 1/4 to 1/6 to its slope for proper drainage.
• The spacing of roof trusses is kept 1/3 to 1/5 of the span.
• Roof trusses usually require very light members.
• A minimum angle section ISA 50 × 50 × 6 mm should be provided to avoid damage during transportation.
• The gusset plate should be at least 6 mm thick and at least 2 rivets should be used to connect any member to it.
