QUESTION $3[20$ MARKS$]$

A tire carries a $22\mathrm{.}2kN$ load and has a pressure of $706\mathrm{.}8$kPa. The pavement that the tire is on

is constructed with a modulus of elasticity of $300$MPa. A deflection of $0\mathrm{.}41mm$ is observed

at a point at the pavement surface, $2cm$ from the center of the tire load. Determine the radial

horizontal stress at this point.
