Plot Comments

  • The lower tire pressure reduced the stress at the 6 and 12 inch depths effectively.
  • The weight of the vehicle means that the stress at the 20 inch depth is not as effectively reduced by lowering the tire pressure.
  • Lowering the axle weight would reduce the stress at the 20 inch depth.
  • The machine was not able to be tested with the boom out due to a technical problem.
