I. Determination of the vertical and lateral pressures of granular substances

Abstract

The investigations which I have the honour to submit in this com­munication have been undertaken to furnish data to engineers and others who are concerned with the erection of structures which have to sustain pressure upon floors and retaining walls, and also to further the objects of science in a field that is believed to be new. Store-houses have been erected, both in this country and in America, which consist of rectangular cells, called bins , and are filled with grain to a height of 50 feet and upwards above the ground.
