yes that is what we're supposed to get, but I'm not getting close to it. Pretty much all I have to do is get the moment of the beam as a function of x for the first half of the beam and the second half. From there, we take the integral twice.
Anyway, I think my first question is, are the...
Homework Statement
Obtain deflection curve in terms of q, L, and EI
Homework Equations
Use the second order differential equation of the deflection curve to solve.
Meaning that the M(x) is the second derivative and you integrate twice to get V1 and V2

From the...
Your mistake is where you take the moment of the uniformly distributed load.
You have "4(10kN)(4 + 4/2)" for the moment of the uniformly distributed load.
You're right that the resultant force from the 10kN/m load will be 4*10 because the load is acting on the 4 meter length. This resultant...

I want to do my HW problem myself so I'll just put some sample values. If i know how to get this one, i'll know how to do the HW problem(s).

I understand that, but this isn't an exam. It's a take home quiz/assignment. It's worth a very small percentage of the overall grade, about 0.7% and I already had half right so you were only helping with 0.35%. Only reason I asked was because the book was of no help and there was no one else I...
It's a sort of take home quiz. The book doesn't go into depth into how to find this sort of info for these shapes. It just explains briefly for 1 or 2 wood boards, and i have 4.
I think you may be right about the X1 being off. I think x1 will just be 10.5ft - 4ft. So x1=6.5ft.
Therefore...

I have no clue. By cutting the pieces, it changes the length. By cutting the cable at c and removing the 2 supports, wouldn't it make all the forces and moments = 0?
So what I'm getting from this is that the maximum tension occurs at AB so I only set σmax=σAB and don't add them with the other member in tension.
Thanks :)
