🚜 Off-Road Vehicle Mobility in Mud, Snow and Sand: Sinkage, Ground Pressure and Traction Lab

Drive a 6x6 wheeled truck and a tracked carrier side by side over thawing mud, snow and sand and see why one digs in while the other floats: Bekker pressure-sinkage, compaction resistance, Mohr-Coulomb thrust, drawbar pull, tyre pressure and winch recovery. Sinkage and capacity are checked against numerical quadrature.
