Answer:
Force on the printing press will be 123.708 N
Step-by-step explanation:
We have given pressure
![P=7.8* 10^4lb/in^2](https://img.qammunity.org/2020/formulas/physics/high-school/zvku9f7vt98imxj8o42flww46bl2978roq.png)
Dimension is given as 6.1 in × 2.6 in
So area
![A=6.1* 2.6=15.86CM^2=15.86* 10^(-4)m^2](https://img.qammunity.org/2020/formulas/physics/high-school/seqefko2drey3cjbcbzucb0vzrcxcp743a.png)
We have to find the magnitude of force
We know that force is given by
![Force=pressure* area=7.8* 10^4* 15.86* 10^(-4)=123.708N](https://img.qammunity.org/2020/formulas/physics/high-school/iyom7eaaqpi1154eebmhbixcnl4f01n7xb.png)
So force on the printing press will be 123.708 N
