Sameer's mother was impressed by the miracle performed by a Baba who did not get hurt even after lying on a bed of nails. Sameer did not believe in Baba's miracle and explained his mother the principle used behind this trick.
What explanation did Sameer give to his mother?

Text Solution

Verified by Experts

Sameer explained that pressure is the force acting per unit area. If somebody steps on a nail, the entire body weight exerts more pressure as the area of the nail tip is less but if some one lies on a bed of nails, the area of contact increases due to which the pressure exerted by the weight of the body is distributed among the hundreds or thousands of nails. Thus the net pressure on a nail is very small.
