A load of $3 \mathrm{kN}$ is acting on a tyre having $150 \mathrm{~mm}$ nominal width. The effective friction coefficient of tyre and ground interaction is 0.6 and the kingpin offset is $10 \mathrm{~mm}$. Assuming the tyre impression on ground as circle of diameter same as the tyre nominal width, the kingpin torque of the tyre in $\mathrm{Nm}$ will be___________
