# Mobile applications for engineers

Applications are developed with extremely user-friendly interface so that the user could generate design models, obtain output data, define personal formulas and convert measurement units. ## Beam

Static analysis of multi-span continuous beam (up to five spans with two cantilevers).

The program is mentioned to carry out static analysis of multispan continuous beam (up to five spans with two cantilevers). The following support types may be defined: pinned support (restrainded Z), support (restrained UY), fixed support (restrained Z, UY) and their stiffness parameters. It is possible to apply the following loads to the beam: concentrated load / moment, non-uniformly distributed load / moment. The output data will contain diagrams of displacements, rotation angles, bending moments, axial and shear forces. To find out ordinates of diagrams at any point of beam, drag across the diagram. ## Frame

Static analysis of the most common plane frames of various shapes.
The program is mentioned to carry out static analysis of the most popular 2D frames of different shape. The user defined dimensions for the frame and its stiffness parameters. The following types of load may be applied to the frame: concentrated load / moment, non-uniformly distributed load / moment. It is also possible to define hinge connection of bars and necessary boundary conditions. The output data will contain diagrams of displacements, bending moments, axial and shear forces. In the Output data you will see: deformed shape, diagrams of forces in elements, tables of forces in bars and tables of nodal displacements. ## Calculator

Advanced set of mathematical functions and options, converter for measurement units, etc.
CALCULATOR program is mentioned to calculate expressions defined by the user as formulas. To input expressions, use appropriate buttons for algebraic and trigonometric functions or the keyboard.
The program also enables you to convert measurement units for the following categories:
– Length
– Area
– Volume
– Pressure
– Force and mass
– Moment of force
– Angle
– Temperature
– Number.
