Otherwise very handy. -- The Reviewer, 2011-02-18 ### ***-- "Lacking" So this app definitely needs more input fields... The only inputs are sigma x and sigma y, which only through trial and error did I figure out was sigma n (normal stress) and sigma s shear stress. In addition there was a field T(x,y). One of the primary use cases of a mohr circle is to find those sigma x and sigma y, so this is kinda backwards for that. Ui design and aesthetics are top notch however. I'll add stars when this app becomes useful. ***update: Please, add support for coulomb failure envelope. And also please add a parameter for pore pressure, making this useful for structural geology. -- Foolio, 2011-01-24 [View all Mohr's Circle reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Apps Similar to Mohr's Circle - [Civil Engineering Pack](https://apptail.io/app/civil-engineering-pack-FAdb/united-states) - [Timber Engineering Calculator](https://apptail.io/app/timber-engineering-calculator-vFUc/united-states) - [Highways & Roadwork Calculator](https://apptail.io/app/highways-roadwork-calculator-TrCd/united-states) - [Beam Calculator](https://apptail.io/app/beam-calculator-MODd/united-states) - [Arc Calculations](https://apptail.io/app/arc-calculations-lwne/united-states) - [Projectile Motion Calc](https://apptail.io/app/projectile-motion-calc-JPaf/united-states) - [International Steam Tables](https://apptail.io/app/international-steam-tables-Obsf/united-states) - [Hydraulic Pressure Calculator](https://apptail.io/app/hydraulic-pressure-calculator-dgKf/united-states) - [Buoyancy Calculator](https://apptail.io/app/buoyancy-calculator-ZGni/united-states) ## Mohr's Circle Available In - [United States](https://apptail.io/app/mohrs-circle-SjSe/united-states) - [Mexico](https://apptail.io/app/mohrs-circle-SjSe/mexico) - [Switzerland](https://apptail.io/app/mohrs-circle-SjSe/switzerland) - [Brazil](https://apptail.io/app/mohrs-circle-SjSe/brazil) - [Malaysia](https://apptail.io/app/mohrs-circle-SjSe/malaysia) - [Colombia](https://apptail.io/app/mohrs-circle-SjSe/colombia) - [United Kingdom](https://apptail.io/app/mohrs-circle-SjSe/united-kingdom) - [China](https://apptail.io/app/mohrs-circle-SjSe/china) - [Dominican Republic](https://apptail.io/app/mohrs-circle-SjSe/dominican-republic) - [Algeria](https://apptail.io/app/mohrs-circle-SjSe/algeria) - [Ecuador](https://apptail.io/app/mohrs-circle-SjSe/ecuador) - [Egypt](https://apptail.io/app/mohrs-circle-SjSe/egypt) - [Hong Kong SAR China](https://apptail.io/app/mohrs-circle-SjSe/hong-kong) - [Indonesia](https://apptail.io/app/mohrs-circle-SjSe/indonesia) - [Israel](https://apptail.io/app/mohrs-circle-SjSe/israel) - [India](https://apptail.io/app/mohrs-circle-SjSe/india) - [Iceland](https://apptail.io/app/mohrs-circle-SjSe/iceland) - [Japan](https://apptail.io/app/mohrs-circle-SjSe/japan) - [South Korea](https://apptail.io/app/mohrs-circle-SjSe/south-korea) - [Kuwait](https://apptail.io/app/mohrs-circle-SjSe/kuwait) - [Kazakhstan](https://apptail.io/app/mohrs-circle-SjSe/kazakhstan) - [Lebanon](https://apptail.io/app/mohrs-circle-SjSe/lebanon) - [Nigeria](https://apptail.io/app/mohrs-circle-SjSe/nigeria) - [Norway](https://apptail.io/app/mohrs-circle-SjSe/norway) - [Nepal](https://apptail.io/app/mohrs-circle-SjSe/nepal) - [New Zealand](https://apptail.io/app/mohrs-circle-SjSe/new-zealand) - [Peru](https://apptail.io/app/mohrs-circle-SjSe/peru) - [Russia](https://apptail.io/app/mohrs-circle-SjSe/russia) - [Singapore](https://apptail.io/app/mohrs-circle-SjSe/singapore) - [Thailand](https://apptail.io/app/mohrs-circle-SjSe/thailand) - [Türkiye](https://apptail.io/app/mohrs-circle-SjSe/turkey) - [Ukraine](https://apptail.io/app/mohrs-circle-SjSe/ukraine) - [Vietnam](https://apptail.io/app/mohrs-circle-SjSe/vietnam) - [United Arab Emirates](https://apptail.io/app/mohrs-circle-SjSe/united-arab-emirates) - [South Africa](https://apptail.io/app/mohrs-circle-SjSe/south-africa) - [Argentina](https://apptail.io/app/mohrs-circle-SjSe/argentina) - [Australia](https://apptail.io/app/mohrs-circle-SjSe/australia) - [Azerbaijan](https://apptail.io/app/mohrs-circle-SjSe/azerbaijan) - [Brunei](https://apptail.io/app/mohrs-circle-SjSe/brunei) - [Canada](https://apptail.io/app/mohrs-circle-SjSe/canada) - [Chile](https://apptail.io/app/mohrs-circle-SjSe/chile) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
