General Engineering Pro

This application consolidates as many as it can of important engineering formulas while giving the chance for the engineer to calculate the formulas through organized ready forms.
the 5 US dollars you're going to pay, are nothing when compared to succeeding in your job or in your exams in university.

Any positive constructive critique is welcome. When you need more modules to be added, we'll be very glad to add them. Please concentrate on important hard to follow formulas when calculating manually. This application is meant to ease calculations without getting lost between the variables of the engineering equation or formula.

Please read the description till the bottom. It's important.

In this application, You can send the calculation results via: 
- Email (at least install Gmail email client for Android installed to get it running) 
- Skype (if installed) 
- SMS (The usual classic mobile messaging).
- A log of all calculations done with a time stamp so you don't have to repeat calculating them.

The application covers the following topics:A table of units.A table of physical constants.Forward and backward conversion between units (more than 50 conversions).

From applied maths for engineers:1
- Geometry area and volume.2
- Finding the location of centroids of important shapes. 3
- Finding the roots of 2nd,3rd,4th, and 5th degree equations with complex roots too.

From electrical and electronic engineering:1
- A module for Ohm's Law . It helps you find either Power,Resistance, Intensity, or Voltage.2
- Resultant sum of either of Resistances, Capacitors, or Inductances whether the grouping is in series or in parallel. you can have up to 10 elements (Which is more than enough)3
- A module to find the change in the value of the motor resistance of the wire windings after getting some heat through runtime4
- Voltage Drop5
- Resistance value using colour codes6
- Wheatstone Bridge7
- Butterworth Tee LC Filters (High pass and Low pass)8
- Chebychev Tee LC Filters (High pass and Low pass)9
- Butterworth equal component Filters (High pass and Low pass)10
- Pi attenuator11
- T-attenuator12
- Helix Antenna Design13
- Battery life14
- BJT Transistor Bias Voltage Calculation15
- Non-inverting op-Amp resistor16
- Zener diode17
- Radar Range

From Mechanical Engineering:1
- Resultant sum of two forces acting at the same point2
- Using the altitude and the latitude given by the GPS in the phone, find the exact value of the gravitational acceleration of the earth.3
- Rectangular Beam Deflection (hollow and solid)4
- Round Beam Deflection (hollow and solid)5
- Internal screw thread shear area6
- External screw thread shear area7
- Cam-with-follower Profile determination. Here you can see both the coordinates of the profile of the cam on a step of 1 degree only, and get the profile plotted so you can see how it would look like.8
- Shear and Shear Force.9
- Cartesian Fluid Flow Analysis.10
- Fluid Drag Force11
- Rectangular Solid/Hollow Beam : Moment of Inertia + Section Modulus + Radius of Gyration (The beam angle of tilting is taken into consideration here too!)12
- Circular/Semicircular/Ecliptic Solid/Hollow Beam : Moment of Inertia + Section Modulus + Radius of Gyration.13
- Beams of cross sections I, C, T, L,Z, X: Moment of Inertia + Section Modulus + Radius of Gyration. Hint: You may use the horizontal I section as an H-section.14
- Interpolations over Steam Tables (pressure and temperature).15
- Heat transfer through walls.16
- Heat loss from pipes wrapped with insulators.Notice: =====The application uses GPS. It's used only in taking the coordinates for the sake of calculations. If you are in doubt that we might steal your coordinates, you can use the manual input option, or just put the GPS off. You are now informed. Thanks.

This version removes the advertisements from the free version of the same application with also more additional calculation activities/modules that do not exist in the free version.
