An experimental expression of the restoring force of a tire compressed by a flat plate and a dull edge is derived. Using this expression, equations of motion of a light truck that runs over a low bar-like projection placed normal to the direction of the motion of the truck are set up. These equations are solved by a numerical method in the situation that the left-hand wheels of the truck run over the projection. Based on the solution, the force applied to the road by the truck in this situation is calculated. Experiments are made to measure the force applied. A force-measuring device equipped with a force-receiving flat top plate is settled in the road with the top plate flush with the road surface, and a bar-like projection is attached to the top plate. The force is measured when the left-hand wheels of the truck run over the device. It is concluded that the results of calculation show good agreement with those of experiment.
