Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company...
Just added a page to the tools, which will allow you to calculate the synchronous speed, slip and rated torque for an induction motor. Not a particularly...
GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:
