Question

Q.3) Solve examples.
1) The area of the tip of a screw is 0.5m2 & it's weight is 0.5N, cal culate the pressure exarted by the screw on a wooden plank .​

Answer 1

Weight = $\bf0.5 \: N \:$

Area = $\bf0.5× {10}^{ - 6}m^{2}$

Pressure = $\large \bf\frac{ \cancel{ 0.5}}{ \cancel{ 0.5 }\times{ \: 10}^{6} \: } = { \color{red}{10}^{6 }Pa}$
