United States currency is printed using intaglio presses that generate a printing pressure of 8.1 x 104 lb/in2. A $20 bill is 6.1 in. by 2.6 in. Calculate the magnitude of the force (in pounds) that the printing press applies to one side of the bill.

Answer 1

force=pressure*area.

curiously, if it applies the force to one side of the bill, the same force is applied to the other side, otherwise the bill has to accelerate. Newtons third law.
