Find the pressure exerted at the tip of ...

Find the pressure exerted at the tip of a board pin, of area 0.1 `mm^(2)`, if it is pressed against the board with a force 15 N.

Text Solution

Verified by Experts

Normal force applied on the pin, F - 15 N
Area of the tip of the board pin, A = 0.1 `mm^(2)`
`0,1xx10^(-6)m^(2)`
Pressure `P=F/A = 15/(0.1xx10^(-6)) Nm^(-2)`
