On the Soil Deformation and Stress by the Lug of Farm Wheel (3)

Abstract

In this paper, the results of the deformation of the soil by the rolling of farm wheel are reported. These wheels have the lug attached with various angle. The photographs in the paper are the few examples of these tests. The soil moving. are effected by the locus of the lug, and the soil moves to the direction of the lug locus. The table shows the details of the test, and in upper part of it, the details of the test of wheels that have the lug attached to the wheel surface and under part of it, the details of the test of wheels that have the lug only are shown.
From upper line of it, Test No., Photograph No., lug angle, the number of lug, the slip percentage at the wheel surface, the slip percentage at the top point of lug, the left letters of next line is written “drawn wheels”, the right is “wheels that draws the load”, last line is the load drawn.
