The Way Things Work - Inclined Planes
In Inclined Planes, inhabitants of Mammoth Island have decided to smash boulders into bits by dropping them off a wooden tower to make gravel for their new roads. While this method does produce gravel, the islanders find it is difficult and even dangerous to hoist boulders up the side of a tower. A young islander, Olive, suggests that they roll the boulders up a ramp instead of hauling them up the tower, and proves that it takes less effort to roll the boulders up an inclined plane, thereby allowing them to get the job done more easily!

Unsaturated Soils: A fundamental interpretation of soil behaviour
Product Description: An understanding of the mechanical properties of unsaturated soils is crucial for geotechnical engineers worldwide, as well as to those concerned with the interaction of structures with the ground. This book deals principally with fine-grained clays and silts, or soils containing coarser sand and gravel particles but with a significant percentage of fines. |
