Question

The vehicle damage factor of a vehicle with single axle load 10 tonnes is 'k' times that of vehicle with single axle load 8 tonnes. The value of k is _________

Answer 1

$\text{Vehicle damage factor}={\left[\frac{\text{axle load}}{\text{standard axle load}}\right]}^4$

$\text{Vehicle damage factor}\propto {\text{(axle load)}}^4$

$\frac{VD{F}_1}{VD{F}_2}={\left(\frac{10}{8}\right)}^4=2.44$
