AI Thread Summary
The discussion centers on confusion regarding calculating the lengths of beams in a cantilever framework practice exam. A participant suggests using a Free Body Diagram (FBD) to analyze the forces instead of needing initial lengths. They explain that the reaction forces can be represented with blue and red lines in the diagram. The key equations to apply are the sum of vertical and horizontal forces equaling zero. This approach simplifies the problem and clarifies the necessary calculations.

You don't need them. Just do a FBD and you will see.
I started it for you. The blue lines are the reaction forces in the beams and the red lines are the components of the reaction force of the slanted beam. Sum of Fy = 0, sum of Fx = 0 ...

Ah thanks for that, much appreciated! Knew I was missing something.jack action said:

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...
