Question

Bhola was impressed by the Miracle performed by Baba Bandar Naath when Baba lie down on a bed of nails. The nails did not hurt him Bhola narrated about this miracle to his friend Hrithik. Hrithik explain to follow that there is no miracle here even he can also do the same trick. Why did Hrithik say that there is no miracle in this trick why did Baba Banda Naat did not hurt himself

Answer 1

Since the area is more pressure is decreased and hence he is not hurt

Answer 2

The 'secret' to this phenomenon is first to understand that it is the force per unit area of skin (i.e., pressure) that determines if a nail will pierce the skin.

The force is determined by the weight of the person lying on the bed of nails.

If there were only one nail, the entire force created by the weight of the body would be distributed over the very small area presented by the tip of the one nail. In this case, the force per unit area, would be very great (because the area is small) and would likely result in piercing of the skin, and injury.

However, when a 'bed' of nails is used, the same force produced by the weight of the body is distributed over perhaps hundreds of nails. Therefore, the force applied to any one nail is correspondingly reduced, with the result that the force per unit area at the tip of any one nail will  be well below the level required to pierce the skin. Since this applies to all the nails in the bed, no nail then penetrates the skin.
