Question

Force exerted by a truck is $500000N$ and the pressure on the ground is $2500000Pa$. Calculate the area of contact of tyres with ground?

Answer 1

Force = $5\times {10}^{5}N$. Pressure = 2500000 $P_a$

Since, Pressure $=\frac{Force}{Area}\Rightarrow Area=\frac{5\times {10}^5}{25\times {10}^5}$

Area = 0.2 $m^2$ (for all four tyres)

& for single tyre area of contact is 0.05 $m^2$
