1. ## 3-D Statics

1. The problem statement, all variables and given/known data
IT IS POSTED IN THE ATTACHMENT BELOW

2. Relevant equations
everything is in static equilibrium

3. The attempt at a solution

well I know how to follow up to solution on these types of problems quite easily, however..on this one I can't seem to get started because I don't know where the weight of the of the pipe is located on the assembly...so

1. i tried multiplying 20N/m by 6.5 (length of the pipe) I think that should give the value of the force

2. I tried finding the centroid of the wire...but the centroid I found isn't even located on the pipe at all which really confused me

so basically all I need to know is where this force is, so I could get started on the problem ...thanks

2. Why find the centroid? Just balance your forces in each plane and apply moments.

3. sorry, I don't follow exactly...

4. Let's try a simpler problem with the same flavor. The picture below is of a mast (black) with a crossbar (red). The crossbar has a weight of 100 N. What is the tension in the support wire (blue)? (Let the length of the crossbar be 2 m.)
