Webangle of repose When they form conical piles, granular materials such as salt, gravel, and sand settle at different angles of repose." depending on the shapes of the grains. One particular 13-foot tall cone of dry sand has a base diameter of 38.6 feet. 1. To the nearest tenth of a degree, what is the angle of repose of this type of dry sand? 2. WebJan 31, 2005 · These are common everyday substances, but they can be vexingly difficult to predict. One moment they behave like solids, the next like liquids. Consider a dump truck full of gravel. When the truck begins to tilt, the gravel remains in a solid pile, until at a certain angle it suddenly becomes a thundering river of rock.
