I have been asked this question in a job interview.

Enquiry is from Simple Trusses in chapter Structural Analysis of Engineering Mechanics

Answer 1

Correct answer is (b) The first part of the statement is false and other part is false too

The explanation: There are various rules used to design the truss. Like the loads must be at the joints only. The use of pin must be there in the joining of the trusses etc. Also the joints must be welded with a gusset plate. And the bridges are also having various rules for their design too.
