Homework Equations
The Attempt at a Solution
I just want to know if I am doing this right... So, my homework is to calculate the members of a truss. So, here i have a picture of a bridge (truss). I am suppose to calculate the member going from U3 to U4. Thus, I am going to cut the section off (the yellow highlighted part) and do a summation of moments about L3, so that i can solve for the member U3-U4.
Is this correct? Since with method of sections, i can just ignore the rest of the bridge and focus on the left side?
Also, is the member U6-L6 (vertical pillar) a zero force member? So that the member's force =0?
