No man is an island


And neither is fluid power. Unless you're buliding a test bench to evaluate or demonstrate a hydraulic or pneumatic component, every fluid power system is connected to some sort of mechancial system. So even though you may have a collection of smartphone apps for making fluid power calculations, you'll probably need apps for the mechancial portion of the machine you're designing.

Mechanical Engineer, part of MultiEducator's iPhone Formulator line, is a useful tool for any mechanical engineer or engineering student. The Mechanical Engineer app contains more than 300  mechanical engineering formulas, plus 300 conversion formulas and 70 area formulas. Major areas covered in the program now include: actuators bearings, fluid power, belts, brakes, clutches, elevators, gears, heat transfer, Iinternal combustion, kinetic energy, metalworking, power plants, refrigeration, shafts, springs, and vehicle drives.

All formulas can be saved, and you can access recently used and favorite formulas. You can also email the results of any formula. If you do not see a formula you want, just email MultiEducator tech support, and they will try to include your request in the next update.
