INTRODUCTION

The objective of this work is first to determine experimentally the horizontal and vertical force components of the operative forces during soil cutting. Since previous work in soil cutting had been empirical and involved curve fitting techniques therefore the second objective is to predict these horizontal and vertical force components. In order to achieve these objectives a special apparatus was designed and fabricated for experimentation. It comprises the soil bin, the horizontal and vertical carriages, the proving rings, carriage seat frame, soil hopper, manually operated jack, and the blades. In order to reduce cost and weight of the apparatus, and also because of the limited space available, the carriages and the cutting blades were made of aluminium.
