Question

A pressure of 1000 Pascal is requried to pierce a wooden block if a sharp nail of area 0.1cm² is used. Calculate the force requried to pierce the wood
Answer:

Force required for piercing the block = 0.01 Newton

Explanation:

Answer 1

Answer:

:

Force required for piercing the block = 0.01 Newton

Explanation:

Given :

Pressure applied, P = 1000 Pascal

Area of tip of sharp nail, A = 0.1 cm²

To find :

Force required for piercing the wood, F =?

Formula required :

Formula for calculating Pressure

       P = F / A

[ Where P = pressure, F = Force, A = Area; in their SI units ]

Solution :

Converting Area given in cm² into m²

→ A = 0.1 cm²

→ A = 0.1 × 1/10000  m²

→ A = 0.00001 m²

Calculating Force required for piercing

Using formula

→ P = F / A

→ 1000 = F / (0.00001)

→ F = 1000 × 0.00001

→ F = 0.01  Newton

Therefore,

Force required for piercing the wooden block is 0.01 Newton.

Answer 2

Answer:

Answer:

Force required for piercing the block = 0.01 Newton

Explanation:

Given :

Pressure applied, P = 1000 Pascal

Area of tip of sharp nail, A = 0.1 cm²

To find :

Force required for piercing the wood, F =?

Formula required :

Formula for calculating Pressure

       P = F / A

[ Where P = pressure, F = Force, A = Area; in their SI units ]

Solution :

Converting Area given in cm² into m²

→ A = 0.1 cm²

→ A = 0.1 × 1/10000  m²

→ A = 0.00001 m²

Calculating Force required for piercing

Using formula

→ P = F / A

→ 1000 = F / (0.00001)

→ F = 1000 × 0.00001

→ F = 0.01  Newton

Therefore,

Force required for piercing the wooden block is 0.01 Newton.
