Question

Ask your friends to pick up their pencils and press their both ends with equal force .which end of the pencil causes more pain to the fingers. why ? What i
s the relationship between surface area of the pencil and pressure experienced ​

Answer 1

Pressure=Force /Area

Force is constant

Then Pressure is inversely proportional to Area

If area is more pressure is less and if area is less pressure is more

So when my friends press the pencil at the ends with same force the person who presses the front portion or nib feels pain because there the area is less and pressure is more.

whereas the downside portion is spherical and has more area so less pressure.
