Building a Test Rig

I need to simulate a test weight of between 10 and 20 Kg on top of a product. I am planning to do this by compression, via a steel plate directly attached to the arm of a pneumatic cylinder. The product, (and steel plate), dimensions are 5 1/2" x 1 5/8", (or 14cm x 4.1cm for you youngsters!). Am I correct in assuming that I need to apply a pressure of between 2.8 lbs/sq in, (0.17kg/sq cm), and 5.6 lbs/sq in, (0.35kg/sq cm), to the top of the pneumatic piston, regardless of the size of that pneumatic piston?

No.

The pressure you need to apply to your cylinder to provide that given force will depend on the cross-sectional area of your piston.
