Stress and strain — practice question

The diagram depicts a large crane on a construction site raising a cube-shaped load at constant speed. A model of the crane, its load and the cable supporting the load is constructed. The material used for each component of the model is the same as that used for the full-size crane, cable and load. The model is one tenth full-size in every linear dimension. What is the ratio $\dfrac{\text{stress in the cable on the full-size crane}}{\text{stress in the cable on the model crane}}$?
