Question

2. Which of the following is a correct
formula to express pressure?
a.
Force
Pressure =
Surface Area
Surface Area
b. Pressure
Force
C.
Thrust
Pressure =
Surface Area
d. Both (a) and (c)​

Answer 1

Answer:

c. thrust

pressure=

surface area

Answer 2

Answer:

Pressure (P) = Thrust/ Area

The SI unit is ‘pascals (Pa)’. 1 Pa = 1N/m2

Example: It is easier to hammer a sharp pin than to hammer a blunt pin. This is because the area at the end of the sharp pin is smaller than the area at the end of a blunt pin. This leads to an increase in pressure leading to hammer the sharp pin easily.
