Question

A force of 100N is applied to an area of 100mm².what is the pressure exerted on the area in N/m².​

Answer 1

P = 1000000[Pa] = 1000 [kPa]

Step-by-step explanation:

To solve this problem we must use the definition of pressure, which is equal to the relationship of force over area.

`P=F/A`

where:

P = pressure [Pa] (units of pascals)

F = force = 100 [N]

A = area = 100 [mm²]

But first we must convert the units from square millimeters to square meters.

`A=100[mm^(2)]*(1^(2) m^(2) )/(1000^(2)mm^(2) ) =0.0001[m^(2) ]`

Now replacing:

`P=100/0.0001\\P=1000000[Pa]`
