Question

calculate the pressure exerted at the point of drawing - pin if it pushed against a board with a force of 20 Newton, assuming the area of the point to be 0.1 millimetre square​

Answer 1

Answer:

P=F/A

Explanation:

F=20 N A= 0.1 mm²= 0.1*10^-6 m²( 1mm²=10^-6 m²)

P= 20/(0.1*10^-6)

=200*10^6

=2*10^8 N/m²

Answer 2

Answer:

the pressure applied by the pin is 200 Pascal

Explanation:

$pressure = \frac{force}{area}$

force =20N. area=0.1mm^2

pressure= 20N/0.1mm

= 20*10/1 Pascal

= 200 Pascal
