Shear Force Diagram (SFD) Generator ● Compute and plot shear force V(x) along a simply supported beam for point loads and UDLs. ● Allow user inputs for beam length, load magnitude, and position; display shear variation and reactions at supports. ● Concepts: Shear force distribution, load–shear relationship, sign convention.

I am farely new to LAB and I was thrown into the deep end with this assignment, all the ways I have thought of haven't worked, can anyone please help me

Hi zak,

what is your question?

(Do you want someone else do your job? Then you should offer payment in the JobOpenings board!)

[thedumbestalive]

I am a student looking for help I don't need someone to do my job, how will I learn?

1. Listen to your teacher.
2. Read the course material.
3. See all those TrainingResources offered at the top of the LabVIEW board.
4. Play with the example VIs in the ExampleFinder (LabVIEW help menu)…

Look I didn't come here for scrutinity, if you dont want help it's okay, don't

I did answer your question to my best knowledge.

We (the active forum members) are "just" voluntary contributors, writing messages on our spare time.

We are willing to help with specific questions.

We also help with homework duties, but don't provide them for free.

You did not ask for any specific problem, you did not show your VI (attempts), you just listed your homework requirements.

So when you want specific help you need to

• provide your current VI
• ask specific questions

When you provide VIs: most active members use older LabVIEW versions, while students often use the very latest version. Please downconvert your VI before attaching: most are happy with "LV2021 or older", I prefer LV2019…

I think you might have had a faulty google search. Are you sure you're asking a "LabVIEW" question?

LabVIEW is a graphical programming language used for test and automation, I wonder if you're looking for a different product and landed here by mistake.

How is any of this related to LabVIEW?

Dear "Dumbest",

     If you look at some of the posts in the LabVIEW Forum, you will find that GerdW is one of the most patient and helpful responders, gently trying to guide students (such as yourself) into learning LabVIEW.  If you have any experience with other programing languages, most of which are "text-based" (C++, Basic, Python), LabVIEW is very different, and you really need to pay attention to class, try making simple VIs to (say) count from 1 to 10 updating once/second (or other routines designed to test how the concepts you should be learning in class actually work).

     If all else fails (and you are unwilling to do your part), drop the class.

What is "LAB"?

Can we assume you understand all the math behind the problem and you are just having difficulty to implement it in code?

How should the output look like (just numbers? Annotated graphics? etc.)

[thedumbestalive]

Sorry its a bad habit of mine to say LAB instead of Lab View, yes I do understand the math, I had tried using the formula node but I getting it wrong, then in plain I kept on messing up on how my Shear force distribution graph will turn out. Formula: RA- sumb4- Wseg, i think i finally made it work

Disclaimer: I am not looking for someone to do my work.

I want help to fix mistakes you might spot
Ways I could implement my formula in formula node
How to declutter my work if possible.
I am not sure if it is possible to restart my arrays, or I am thedumbestalive
This isn't part of the project but, Might anyone have an idea how I could instead of enter my data in arrays could I interactively do it using a UI whereby i have a beam figure and the user can add the forces like in the attached figure.

I apologize for how i structure my message it the beginning, I should have done this first
