Hi,
I just wanted to thank everyone for the quick and interesting responses.
For now, I used 4 discrete cross sectional shapes instead of four. This resulted in 8 equations, so my system of 8 unknowns could be solved.
I will look into the other methods proposed on this forum out of interest...
Dear Greg,
Thanks for the lightning fast reply.
I should have clarified, I have already calculated reaction forces and constructed my shear and moment graph. I was now trying to implement the three different cross sections.
That said, I will take a look at macaulay's method, thanks!
Hi all,
I am new on this forum. Im a mechanical engineering masters student.
For an assignment, I am designing an overhanging beam, and optimizing it for weight.
Due to production and material choices, we went with U (channel section) beam.
To minimize weight, I want to vary the cross...
