AI Thread Summary
A beam diagram can be applied to real-life structures by modeling components like gantries or machine shafts supported by bearings. The discussion highlights the need to compare theoretical calculations of strain and deflection with practical measurements taken during experiments. Participants suggest using examples such as motorway gantries or machine shafts with weights from components like flywheels and pulleys. The conversation emphasizes understanding the similarities and differences between static load theories and real-life applications. Overall, the goal is to illustrate how these theoretical models can accurately represent real-world load-carrying structures.

Hi folks
I was wondering if someone can start me off on this question, I have have a line diagram of a beam and I have to use it to use in a real life example. I don't know what to use and compare it to would be grateful for some of you guys input.Give an real example/picture of a load-carrying component/structure and show how the system
could be modeled using a beam. Describe the differences and similarities between the static
load theories that you know and what could happen in real life.

The question really is not clear. Could you try stating it again in different words?
 
The beam in the PDF file is a beam that was setup and we did a practical experiment on it, we hung weights at 3 points which was wb, wc and we there was a strain gauge and a meter to read the deflection. Once the weights were on we took readings of the strain and deflection the diagram shows where the strain gauge was positioned. Once we obtained a few results, we used the Mcauley methods to calculate the strain and deflection theoretically and then compared the results for accuracy.

Now the question is asking me to give an example/picture of an load carrying component/ structure and show how the system could be modeled using this beam. I have to discuss the similarities between the static and load theories, and what could happen in real life. One example some one told me to use was the gantry on a motorway, again I just wanted to know how a gantry could be modeled using a beam system and the effects.
 
One example would be a machine shaft on three bearings. Wb, Wc, We might be the weights of the supported components, such as flywheels, saw blades, electrical machine rotors, pulleys, etc.

Could you please go into abit more detail please?
 
What more do you want? If you don't see the connection, may I suggest that you look on Google for pictures of machinery shafting.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search 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...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

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...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

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...
