A drawing pin (thumb tack) has a sharp point and a flat end.
The pin is pushed into a wooden board.
How do the pressure and the force at the sharp point compare with the pressure and the force at the flat end?
1 )
force at the sharp point:greater than at the flat end / pressure at the sharp point:greater than at the flat end
2 )
force at the sharp point:greater than at the flat end / pressure at the sharp point:less than at the flat end
force at the sharp point:the same as at the flat end / pressure at the sharp point:greater than at the flat end
4 )
force at the sharp point:the same as at the flat end / pressure at the sharp point:less than at the flat end
