I major in microelectronics. I just want to apply a fixed and adjustable force to my flexible sample.
- 'Fixed' means that the force could be hold for given time without change.
- 'Adjustable' means that the force would be changed after my setting or its value could be changed with time and rule.
It would be better if the force was horizontal.
My sample can endure the force with value about 10 N. And I hope the force could be adjustable between 0 and 10 N.
I think a stepper motor with load cell may be the solution but I don't know how to realize it exactly. The only thing I can think of is to hang different balance weight to one side of my sample. I know some kind of universal testing machines could also get this done but they are too expensive.
