That includes moment of inertia, modulus of section, radius of gyration, area and weight. The calculations are done in both principal axes. This program is particularly useful for analysis and design of indeterminate structures and for calculating actual and allowable (permissible) stresses of structural members (beams, columns, etc.). The input is top flange width, top flange thickness, bottom flange width, bottom flange thickness, web depth and web thickness. The top flange and bottom flange dimensions can vary. You can select a section from a large library of hot rolled shapes: European IPE, HEA, HEB, HEM and American W shapes Canadian W metric shapes and British universal beams and columns (UB and UC shapes). More shapes from other countries will be added in the next releases. The input can be in mm or inch units, the output of area, Ixx, Sxx, Sxt, Sxb, Iyy, Iyt, Iyb, Syy rx, ry, rt, rb, Syt, Syb, depth and neutral axis can be displayed in mm or inch units. The weight can be displayed in kg/m or Lb/ft. This is a light version with limitations: The hot rolled library contains selected American shapes only and the built up section can have only equal top and bottom flanges. For the full version see iSection in the App Store. See also iConcrete in the App Store which designs single and double reinforced concrete rectangular and T beams. ## Key features - Calculates moment of inertia, modulus of section, radius of gyration, area, and weight - Supports European, American, Canadian, and British steel shapes - Input and output in mm or inch units - Calculations in principal axes - Light version with limitations on hot rolled library and flange dimensions ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/isectionlite/id320141628/reviews.md ### 1/5 — Weak interface. Very limited. *2009-09-21, version 0* After thinking: what do I do? I tried clicking the blue texts, and ah! Here's where I enter data. Now, the section name typing instead of simply picking is plain wrong. ### 5/5 — I'm First *2009-06-23, version 0* Great app ## Frequently asked questions about iSectionLite ### What structural properties does iSectionLite calculate? iSectionLite calculates key properties such as moment of inertia, modulus of section, radius of gyration, area, and weight for built-up section members. ### What types of steel shapes are supported by iSectionLite? This version supports selected American hot rolled shapes. It also includes European IPE, HEA, HEB, HEM, Canadian W metric, and British universal beams and columns (UB and UC shapes). ### Can I use iSectionLite with both metric and imperial units? Yes, the input can be in mm or inch units, and the output for various properties can also be displayed in mm or inch units. Weight can be shown in kg/m or Lb/ft. ### What are the limitations of the iSectionLite version? The iSectionLite version has limitations. The hot rolled library is restricted to selected American shapes, and built-up sections can only have equal top and bottom flanges. A full version is available. ### Is iSectionLite available on Android devices? Based on the provided data, iSectionLite is supported on iPhone and iPod Touch devices, indicating it is an iOS application. ### How often is iSectionLite updated? The application was last updated on January 23, 2017, to version 1.21.
