Problem 13PE
Nail tips exert tremendous pressures when they are hit by hammers because they exert a large force over a small area. What force must be exerted on a nail with a circular tip of 1.00 mm diameter to create a pressure of 3.00×109 N/m2 ? (This high pressure is possible because the hammer striking the nail is brought to rest in such a short distance.)

ANSWER:
Solution 13PE:
Step 1 of 2:-
Here we need to find the force exerted on the nail by the hammer which creates certain amount of pressure.
The tip of the nail has a diameter of .
So, the radius is, .
So, the area of the circular tip will be,
.
The pressure created is,
.
