Hi,
I Have a Fitness equipments repair test and have to passed.I have 48 hours to find asnwers before send them back. I have trying to figure out answers for each questions but it takes really long time because each questions means 30 minutes of research online.
It's mostly about fitness machines,motors and motor controllers
Do you guys any idea how can I find answers/informations for these kind of questions?
Or it may be some sort of technical website that I can get help from.
PLEASE HELP!!
THANK YOU
