This app means that you will always have all the key formulae and tables on screen, no matter where you are, and will be able to roughly calculate simple drive systems quickly and easily. Basic formulae for kinematics, dynamics or forces and torques as well as work, power, energy and control technology are included, and can be filled with data at any time.
So you can calculate a drive design in advance using your mobile device, store the results and use them again for further analyses. Great when it's this easy!
Give it a try - it makes sense!
