Book Description
This interim report covers tests to determine correlation between scale-model and full-size, 4 x 4, pneumatic-tired vehicles operating in sand. Test results demonstrate that the mobility performance of prototype wheeled vehicles can be accurately predicted by tests on scale-models using the techniques described. Tire selection data for 4 x 4 vehicles are presented covering the full range of sand strengths found in nature, tire loadings from 50 lb. to 50,000 lb., and sizes from 2' to 10' in outside diameter and 0/20 to 1.00 in width/diameter ratio. Means for estimating sand strength for design purposes are also indicated. A simple relationship between tire performance in sands and dry snows is also demonstrated. (Author).

Book Description
Scale Models in Engineering: Fundamentals and Applications provides a simple and fundamental method of designing scale model experiments. This book is divided into two parts. Part I explores the background of scale modeling and explains the design procedure of scale models and experiments. The relaxation method commonly applied to conflicting requirements in model design is also analyzed. Part II is devoted to case studies selected from modern fields of model application. These studies have been interpreted uniformly. This publication is designed not only as a college textbook for senior and graduate levels but also as a working reference for practicing engineers.

Book Description
Tests were conducted in snow with six reducedscale tires. The tires covered a wide range of width-to-diameter ratios. The results are expressed in dimensionless terms and are applicable for a range of vehicle sizes and weights as well as a range of dry snow conditions. Tests described in previous reports have covered the flotation type of performance. Tests described herein cover the performance of two types of tires for the ground-supported (limited snow depth) type of performance and, also, the results of additional flotation tests. The complete flotation data, including that from previous years' tests, are summarized and further analyzed. Present data are limited to 4x4 vehicles with equal weight distribution. The possibility is shown that data for vehicle tests in sand can be interpreted in terms of performance in snow. Results of a preliminary snow survey, which can be used to predict vehicle performance in subarctic, below-thetree-line snow regions, are shown.
