Machinist approved This app is well worth the money. Even though the guys I work with and myself learned about chords in school none of us could remember how to calculate them. This app is a chord calculating genius.

## Pocket Geometry LITE

Pocket Geometry LITE (Formerly GeoCalc LITE) is a sample of high quality geometry calculation tools. This tool will help you calculate angles in polygons, circumference in circles, area in circles, length of arcs, angles in triangles, area of rectangles, and perimeter of rectangles. The full version includes many more tools and will be updated more often.

## Area Calculator

Calculating area is a key to everyday life. From math homework to finding square footage, calculating area can be time consuming and difficult. First, you have to remember the formula. You don't remember so you search it online. Once you got the formula, you have to plug in the numbers. After that, you have to do math. At the end, you found out you forgot to carry the one, and your calculations were nowhere close.

BUT, if you have used the Area Calculator, the amount of time it took to plug in the numbers is the same amount of time it would take to get an answer with this app!

This app can calculate the area of 4 SHAPES! With these 4 shapes, you can find the area of almost any shape.

Visual learner? NO PROBLEM! This app also utilizes diagrams!

And, did I tell you that this app is free?

Features:

-Find the area of a triangle, rectangle, trapezoid or circle

-Diagrams for the visual learners

## I-Beam/H-Beam Calculator

This is a simple calculator that calculates the geometric properties of an I beam (also known as an H-beam, W-beam or Wide Flange Beam).

To use this app, enter the Flange Thickness, Flange Width, Web Thickness and Depth of the beam (diagram of what each dimension refers to is above with the screenshots). The app will then calculate the cross sectional area of the beam, as well as the Moment of Inertia, Radius of Gyration, and S for both the x-x (strong) and y-y (weak) axes, with units consistent with those inputted. It may be necessary to scroll down to see all of the calculated numbers.

If you wish to calculate Q, then you must also select the axis that you would like to calculate Q in relation to. The default is the x-x axis (strong axis), and this is almost always the desired choice. If you wish to calculate Q at a point that is not on the centroidal axis, you may also enter a distance in the "Distance from Centroid:" field corresponding to the location of your point.

This app is particularly useful for students in mechanics of materials, or others wishing to calculate stresses in a beam. If you found this app useful, you may be interested in my other apps, Shear Stress Calculator - Tube (available https://play.google.com/store/apps/details?id=com.davidschack.shearstressinhollowtube.app) and Equivalent Resistance Calc.

## CG Calc

RC Model Aircraft Center of Gravity Calculator v2.3 (replaces v1.x)

--------------------------------------------------------------

Note 1: Potentially not compatible with some versions of Android 5.x (Lollipop) yet, please try it out to be sure, I am trying to find a solution. Apologies to those who have updated to Lollipop and find the app behaves strangely.

Note 2: please email if you have a problem or suggestion

Note 3: This app was built with MIT App Inventor, the permissions* (see below) required are the defaults, I have no control over what permissions Google/MIT App Inventor requires an app to have. This app has been published on Google Play since 2012 and since it is still here you can be assured that Google Play has no problems with it.

Note 4: Please see also my RC-E Calculator which includes wing loading, flight time, prop thrust and other calculators:

► RC E Calc Pro

--------------------------------------------------------------

This may prevent your plane from crashing!

This app will calculate the POSITION of the Center of Gravity (CG or CoG or Balance Point) measured back from the leading edge at the wing root.

Enter your measurements for:

- tip chord length,

- root chord length,

- sweep length and

- required CG percentage (eg 25%)

of your model airplane and then the CG, wing area, geometric mean chord and tip-to-root chord ratio will be calculated automatically, no tapping required.

You can use inches or centimeters and the result will be in the units you used (don't mix units though).

A too rearward CG position can cause unrecoverable (potentially fatal) instability!

25-30% recommended for most conventional wings, 12-18% for flying wings, 15-19% for Delta wings.

Thanks for downloading and comments welcome.

## Measure Threads with 3 wires

Sometimes it is not possible to use a thread measuring micrometer to measure screw threads, so the measure over three wire method must be used.

Use this application to quickly and easily do all the calculations required to measure ISO metric and UN 60 degree threads, Acme and Stub Acme threads, and Trapezoid threads with wires. The only thing it can't do is help you to hold the three wires in place AND use the micrometer at the same time!

You start with the nominal thread size, thread pitch (or TPI) and wire size.

You cancalculate pitch diameter or measurement over wires or both.

The thread measurement over wires calculator will also give you the best wire size.
