Question

Suppose a force of 1.00 x 104 n is put on a 10.0 cm by 10.0 cm square. What is the pressure?

Answer 1

`P=1000000Pa=1MPa=1000kPa`

Step-by-step explanation:

When the force that is applied is normally and uniformly distributed on a surface, the magnitude of the pressure is obtained by dividing the force applied on the corresponding area:

`P=(F)/(A)`

Where:

`P=Pressure\hspace{3}in\hspace{3}Pa.\\F=Force\hspace{3}in\hspace{3}N\\A=Area\hspace{3}in\hspace{3}m^2`

Converting cm to m:

`10cm*(1m)/(100cm) = 0.1m`

The area of a square is:

`A=l^2=(0.1)^2=0.01m^2`

Therefore:

`P=(1.00*10^4)/(0.01) =1000000Pa=1MPa=1000kPa`
