I'll volunteer --
area of a piston is pi*r*r ("pi times radius squared")
area of 2 in dia piston is 3.14*1.0*1.0 = 3.14 square inches
area of 3 in dia piston is 3.14*1.5*1.5 = 7.07 square inches
force = pressure * area = 12 tons = 24000 lbs
24000 lbs / 3.14 square inches = 7643 psi
24000 lbs / 7.07 square inches = 3395 psi
HTH.
Donald.
