Question

A stone thrown with a force of 60n hits a pin of area 0.06m2. calculate the pressure on the pin.

Answer 1

Given:

• Force = 60 N

• Area = 0.06 m²

To be Calculated:

Calculate the pressure on the pin.

Formula used:

$\sf{Pressure = \frac{Force}{Area} }$

Solution:

$Pressure = \frac{Force}{Area}$

$= \frac{60}{0.06}$

$= \frac{ \cancel60 \times 100}{ \cancel6}$

$= 10 \times 100$

$= 1000 \: Nm {}^{ - 2}$

Extra information:

• Pressure is the force acting perpendicularly on a unit area of the object.

• S.I unit = N/m² or Pascal (Pa)

Pressure depends on two factors:

1. Force Applied
2. Area over which force act .
