How to derive equation of deflecting curve for a simple beam
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...- Blugga

How to derive equation of deflecting curve for a simple beam
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 The Attempt at a Solution From the...- Blugga

Calculating support reactions in a beam
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...- Blugga

Which wood cross section can carry highest uniform load
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...- Blugga

Which wood cross section can carry highest uniform load
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...- Blugga

Help. Shear force and bending moment problem makes no sense
Homework Statement Homework Equations ƩFx=0 ƩFy=0 ƩMo=0 The Attempt at a Solution 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?- Blugga

Finding elongation of bar and maximum tensile stress
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 :)- Blugga
