•  double the force.
•  square the force.

gyorwarth asking:
•  Hi, I could do with some help on this question. I have not see this method of specifying a ram and piston combination. What is the difference between a "2 in2" and a "4 in2" piston, are the designations relating to piston and rod diameter? Thanks, Graeme.
