A steel nail has a large flat head at one end and a very sharp tip at the other end. The nail is hammered vertically into a wooden block.
How do the force and pressure at the sharp tip compare with the force and pressure on the flat head?
Force at the sharp tip is the same as on the flat head; Pressure at the sharp tip is greater than on the flat head
Force at the sharp tip is the same as on the flat head; Pressure at the sharp tip is less than on the flat head
Force at the sharp tip is greater than on the flat head; Pressure at the sharp tip is greater than on the flat head
Force at the sharp tip is less than on the flat head; Pressure at the sharp tip is the same as on the flat head
