Looking at this closely.. there's no way that the solution is correct. My TA must have been mistaken. Thanks for looking at my question

Hi, I am a civil engineering student currently taking Statics. We are doing truss analysis in the class right now; and I know that this joint is marked as correct. However, I don't see how this is even possible. I begin by considering this a concurrent 2D force system, Fy = 0 & Fx = 0. The...

Thank you for the help. I finally got the problem! Well.. at least part A. I know from personal experience that it would be best for me to post my work after I got the answer, so here I have it attached:

Φ=qenclosed/ε0 qenclosed=6.3x10-9 C/m (Just realized this is C/m instead of only C. What does this mean?) ε0=8.85x10-12 F/m. [6.3x10-9 C/m ] / [ 8.85x10-12 F/m = 711.86 C/F]. What is C/F? Coulombs per Farad? I think the unit I am looking for here is N/C, but please correct me if I am wrong...

At this point I want to clarify that obtaining the Gaussian surface is not where I am struggling- rather, it is what to do with said Gaussian surface whenever there is another, oddly shaped electric field acting upon it. How do I generate a net field from that? I have attached a rudimentary...

I imposed my own Gaussian surface using a cylinder centered at the wire with a radius of 1.2 cm. I used the formula Φ = qenclosed/ε0. I ended up with an electric field of 711.86 N/C. To clarify, should I superposition this value with the outer tube's electric field? Or, when the question is...

Thank you for the welcome. Say I created a Gaussian cylinder with a radius of 1.4 cm, centered at the infinite wire, with a finite length of 10 cm. Would this provide me with the answer I am seeking? Or, would I then superposition that field value with the given charge of the outer cylinder?

I have no idea how to approach the problem using Gauss's Law. I found the electric field using superposition, and it was incorrect. I am assuming you treat the wire as a continuous electric field, and then also treat the pipe as a continuous electric field. I solved for this using...
