Please check out Android Smart Phone App, Mecalk on Google market. I've made it and just updated it today. Mecalk helps MecaEng student, entry&professional who donot wanna carry calculator,databook.

It contains around 14 Mechnical Engineering Formula Calculation, 5-6 major components data sheets, and 15 major componet galleries. I also put English caption for English speakers.


it c ost just 1$ and can be used instead of Engineering calculation and thick data book in schools, factories, and companies.
