Homework Statement
A small square truss shown is supported by a pin joint at I and a roller at A. Label all members of the
truss by Z (for zero force member), C (for compression) or T (for tension).
Homework Equations
The Attempt at a Solution
So this was an exam question on a past test and I have troubles understanding how to calculate this in a fast manner.
I usually just use method of joints for each member and determine it that way. But I don't know how to determine tension/compression by looking at a truss. I've asked a couple people but I never understand what they mean...
What is your guy's approach/thought process when solving this problem?
My next exam is coming soon and I really hope to get a better understanding of this!
Thank you very much.
