Off road mobility using terramechanics. Pt. 2a - unpowered wheels

In this series of videos we investigate off road mobility using terramechanics techniques.
Using terramechanics we can look at the factors which affect the off road performance such as soil types, wheel loads, tyre sizes and inflation pressures.
In this video we develop the equations and the soil properties needed to analyse the behaviour of unpowered wheels off road.
Warning - contains technical information (but nothing that interested viewers won't be able to follow).
