United States currency is printed using intaglio presses that generate a printing pressure of 7.8 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.

Respuesta :

Answer:

Force on the printing press will be 123.708 N

Explanation:

We have given pressure [tex]P=7.8\times 10^4lb/in^2[/tex]

Dimension is given as 6.1 in × 2.6 in

So area [tex]A=6.1\times 2.6=15.86CM^2=15.86\times 10^{-4}m^2[/tex]

We have to find the magnitude of force

We know that force is given by

[tex]Force=pressure\times area=7.8\times 10^4\times 15.86\times 10^{-4}=123.708N[/tex]

So force on the printing press will be 123.708 N
