Compute distance and bearing using Maidenhead location. This was originally intended for use by amateur radio operators who participate in microwave communications however it can be used by any ham in order to determine a distance and bearing to another radio amateur. If you want to see maps of the source and target with annotations and overlays as well as be able to touch the map to determine the grid at a particular point, then take a look at our App: DBHamPlus.

Determine capacity of structural steel beam and column easily and obtain results and calculation sheets to double-check your work!! This is a great tool for civil engineers. You will find it useful to calculate capacity of built-up beam and column. The design is in accordance with the provision of AISC 360-16 which is the latest version of design theory. INTUITIVE TOUCH-BASED INTERACTION Quickly place dimensions of the built-up beam or column, and select the steel grade using a simple graphical design. Out solver algorithm will automatically solve and determine the capacity Immediately see what the maximum capacity of the section and also generate calculation sheet to see the calculation details and procedures simultaneously. The calculation sheet will be in .jpg form and automatically saved into your photo gallery. DOUBLY SYMMETRIC AND SINGLY SYMETRIC SECTION AND BUILT-IN MATERIALS Flexible dimensions can be placed to define the size of the section directly. The built-in databases of materials are also provided, including yield strength of 370 MPa, 420 MPa and 500 MPa CONTACT We want to hear from you!! Issues, questions, or requests?
