Do bending moment and shear forces are dependable on a beam's cross sectional area?
Are Bending Moment and Shear Force Dependent on Beam's Cross Sectional Area?

AI Thread Summary
Bending moment and shear forces are not dependent on a beam's cross-sectional area. The bending moment is derived from the shear force curve, which in turn is derived from the load curve of the beam. This relationship indicates that cross-sectional details are not necessary for drawing shear force diagrams (SFD) and bending moment diagrams (BMD). The discussion highlights the importance of understanding these foundational concepts in structural analysis. Overall, the focus remains on the mathematical relationships rather than the physical properties of the beam's cross-section.

Hi,
I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere.
The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary
The bubble is formed at the tip...
Scenario 1 (figure 1)
A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material.
The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm).
At this level of stretch, the load cell reads 45N tensile force.
Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype.
There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/
but none that address the overall topic (unless I've missed...
