1.168e+000 = 1.168 x 10^0 = 1.1668 x 1 = 1.168
8.504e-001 = 8.504 x 10^-1 = 8.504 x 1/10 = 0.8504
I often change my 'chart options' / 'format' from 'scientific' to 'floating' for easier interpretation.
Perhaps you are triggering the 'large displacement' flag; otherwise the results would be linear and 20/30 would be equal to 0.8504/1.168
This is a perfect study for beam elements.
Your beam appears to be fixed on each end, and not just 'supported'.
You should check your calculations with Roark's formulas for beams, or by using an online beam calculator.
I looked for an online beam calculator, but what i found was for standard c-channel shapes, and nothing this small. I will be playing around with a few different shapes. We will be custom extruding the profile once we find what strength works.
As far as the fixed ends, my VAR helped set this up, and the way he did it was to fix the one end in all directions using just the bottom edge. This allows the end to flex. On the other end, he fixed it up and down, but allowed it to slide in and out, so the beam is able to shorten as it flexes. Do you think that should work?
It sounds like the fixture was considered appropriately, so it's likely to be correct.
The important characteristic of the beam is its area moment of inertia. You can find that using the SW 'section properties' tool. You can then plug that into the appropriate formula or online calculator to determine the beam's performance.
Thanks Keith. I was not aware of that tool for measuring the properties.
