TI-Nspire / Static3D
« on: November 13, 2018, 10:02:35 am »
Hello everybody,

Today i'm bringing to you a 3 axis structural analysis made for help you to obtain the Forces and momentum equations once you make the free body diagram.

This is only a fast v1 so feel free to comment, i'm planing to make it even do the free body diagram wich I will probably need help to do.

To use only input the forces of each node [ax,ay,az] and their position A[x,y,z] and the program will calculate for you the equations.

Hope you like it.

P.D: Also works with 2D problems.

TI-Nspire / Electric Circuit Calculation

Hello omnimaga users,

I'm opening this topic to discuss/brainstorm/beg for help because I have in mind to create a program to solve circuits.

For those who don't know what i mean with solve circuits i will explain myself. When you elaborate a circuit you end knowing what intensity, voltage, resistance and power you have on each branch, node and object using the Kirchhoff Laws of current and voltage combined with the Ohm law. Basically an equation system. ( For more info )

The idea is to elaborate a program in wich we can "draw" our circuits and it will be able to find the nodes and branch and after that calculate all the enigmas of the circuit.

What's the problem? Don't know how to do the part for insert the data / draw the circuit, because the most common scenario will be always you have a circuit and some data known and some missing data. I assume the calculation part will be the easy part (I assume... probably wrong).

Hope someone could give me a hand with this project.

Thanks for your attention.

General Calculator Help / Thermodynamic Cycles Program
« on: December 26, 2016, 11:22:27 pm »
Hello everyone;

I'm starting this topic because i want to start a project which could be (or at least I think would be) interesting and useful. The project is based on the AssTermo-D and the main propose is to create a Thermodynamic Cycles program which could be useful to all students with Technical Thermodynamics.

Basically, insert the objects (furnace, compressor, turbine, exchanger...) to create the cycle that the user wants and specify some of their attribute (efficiency, pressure, temperature, work...) to do the main calculations, providing the fluid properties from the AssTermo-D archive which is a great source.

I've the knowledge of what calculations have to do but no idea of programming (and don't know which type of code will be better if C, Lua, Basic...), anyone have interest on helping me or guide me?

Thanks for the attention.

P.D : I got the idea from this old HP48 file I didn't prove it cause don't know how to open it but could be useful.

General Calculator Help / How to create a C program for Nspire CX CAS?

Hi everyone,

I'm opening this post because i want some help to write a program in C for the TI Nspire (actually I have in mind a few programs... ) but first thing first... How it's done?

How do you do to write a C program for the Nspire? (I started trying to install the Ndless SDK but ended on a big failure and I don't know how to do it properly :banghead:)

Thanks omnimaga community

TI-BASIC / Routh-Hurwitz Matlab to TI-Nspire
« on: October 24, 2016, 02:22:04 pm »
Hello everyone,

I'm opening this topic for asking for help, because yesterday i found a very precise script for finding the Routh-Hurwitz of a function. Those were good news, bad news: it's a matlab script.

Anyone knows how to convert this script to Basic or LUA (don't know wich will be better)

The link to de matlab script:

Hope anybody had any kind of info to help me... Thx
