# Description

Never leave the house without your Math in your pocket! Pocket Formulas is the best solution for studying Math. It helps you study, practice and write your Math homework easily! Always carry the formulas you need.

***IMPORTANT***

*This is the old Pocket Formulas App. A terrible thing happened so I had to upload it as a new application.

*That means if you have the old version, you cannot get an update. Simply delete the old version and install

*This one. Thank you for downloading!

You must install this app before submitting a review.

Back Button There is No Back Button in your app, however its a good effort, whenever i want to go back to menu the App just goes off, and i have to start it again, Fix this Gud Luck

Brane Petkoski

Love new design Much better look than old one. But... There is anoying MathJax loading, hide that message man,I think its one line of code (messageStyle: "none") . Second , I am seeing code(javascript I believe) and then formulas. Show blank page,spinner or something , nobody want to see code. Five stars for great redisign.

Jane Lameski

Good Your program don't have all the main formulas. Ex: area of cone, all of the addition-subtraction formulas and multiplication between sin and cos ex: (sin(a)*sin(b))=(cos(a-b)-cos(a+b)) in trigonometry :)

Try exiting the app, then turn it on again. (I know... it works on the second time). If it works you can update your review :) Anyway I don't really have much time to work on this app, but I posted the source code on GitHub and if someone provides me with the solution I'll make an update. Thank you for your honest rating :) Lazar Nikolov March 11, 2014

Thanks Stefce :D Pozz Lazar Nikolov March 27, 2014

Thanks Brane! Lazar Nikolov March 10, 2014

I know. That will happen in future ;) Lazar Nikolov December 15, 2014

We're currently developing a new version of Pocket Formulas, whole new design and lots of new and improved features! When we finish it, you guys will have the ability to write your own formulas so we can make a large database of math and physics formulas. Also we've improved the performances of the app too, now the scrolling will not be buggy :) Lazar Nikolov June 13, 2014

Fala Nevena! :) Lazar Nikolov April 14, 2014

Thanks Chester! :) Lazar Nikolov June 6, 2014

## Shear Forces Bending Moments

MNQ, finds shear forces and moments functions by using the method of sections and draws diagrams of these functions for isostatic straight beam.

Features:

MNQ gives solution for

Cantilever beam (A cantilever beam is fixed at one end and free at other end.)

Simply-supported beam (That has pinned support at one end and roller support at the other end.)

Overhanging beam (That has one or both end partions extendeing beyond its supports.)

Loads can be

Concentrated forces,

Moments,

Distributed loads (uniformly, triangular, trapezoidal)

-In the first time run, MNQ creates a directory on your device's SD card. Your examples can be saved in mnq directory (If you want). You can find the saved examples in the mnq directory and open them touching on.

-After entering the beam length, boundary condition and loads, system becomes can be solved. First, reactions at supports are determined.

-After the reaction forces were known, the beam is cut at the location where discontinuous points (where point forces, reaction forces, at start and end of distrubuted loads e.t.c). Shear force and moment functions are calculated for each section. Calculation steps are shown in orderly.

-Known functions of the shear force and moment are drawn. Some values of functions are shown on diagrams.

-You could share your saved problems with your friends via e-mail or bluethooth.

-If you touch the file extension of the file mnq in file explorer program, MNQ opens and solves it.

-If you open saved files in MNQ's editor, you can edit and save them.
