Question

A pressure of 200Nm-2 is developed on a square surface due to a force of 1800 N acting normally to the surface. Determine the length of the surface.

Answer 1

Answer:

Pressure will be - 20 N/m² and 40 N/m².

Pressure is defined as "continuous physical force exerted on or against an object by in contact with it."

Pressure occurs when force acts

perpendicular to the area.

Pressure is calculated by the formula - Force/ Area

Given values in the Question are - Force -

200N

Area - 10 m² and 5 m²

Now, calculating pressure -

P for 10m² area is -

P = F/A

P = 200/10

P = 20N / (m ^ 2)

P for 5m² area is -

P = F/A

P = 200/5

P = 40N / (m ^ 2)

Thus, pressure for two different situations are - 20 N/m² and 40 N/m².
