A nail is driven into a wooden board by using a hammer. The impact of the hammer on the head of nail produces a thrust of 25 N. If the area of the head is 0.5 mm2 and of the tip 0.1 mm2, find the pressure on the head and the tip of the nail.
Question
A nail is driven into a wooden board by using a hammer. The impact of the hammer on the head of nail produces a thrust of 25 N. If the area of the head is 0.5 mm2 and of the tip 0.1 mm2, find the pressure on the head and the tip of the nail.
Solution
To solve this problem, we need to use the formula for pressure, which is Pressure = Force/Area.
-
First, we need to convert the area from mm^2 to m^2 because the standard unit of area in physics is m^2.
1 m^2 = 10^6 mm^2
So, 0.5 mm^2 = 0.5 x 10^-6 m^2 and 0
