The Distribution of Angle-of-Repose Data
Journal of Geoscience Education, 1998Disinterested physical geology students can be enticed into performing an experiment that takes them though the scientific method and utilizes math skills if offered extra credit. The experiment causes students to compare the angle of repose of different substances, by measuring the heights and diameters of individual piles.

Angle of Repose of Snow on Solids
Nature, 1940IT is well known that the friction of solids on snow surfaces is larger than on ice surfaces. The higher kinetic friction obtained on snow is attributed to the extra work done in displacing and compressing the snow crystals1. This may apply to the sliding of a ski or a sleigh on snow.

ANGLE OF REPOSE: AN INTERDISCIPLINARY LIVELY APPLICATION PROJECT
PRIMUS, 2002A mathematician and a geologist team up to write an interesting interdisciplinary statistics application. While primarily focusing on whether piles of debris composed of different grain sizes have different angles of repose, the project quickly blossomed into a lively study of experimental design and sensitivity analysis.

Characterising Semi‐Cohesive Powders using angle of repose
Particle & Particle Systems Characterization, 1996AbstractWhen properly measured and interpreted angle of repose (AOR) can be a useful method of characterising a powder. Unfortunately, a multitude of definitions and measuring equipment is used. A review of the inherent problems is presented in the first part of this paper.The second part of the paper describes the improvements made to a measuring ...

The angle of repose of potash pellets
Powder Technology, 1974Abstract The angle of repose of a granular medium is shown not to be a unique property of the mateial, but rather to depend on the deposition and storage conditions of the medium. It may consequently be varied by varying these conditions. A knowledge of the angle of repose of potash pellets was required for purposes of intercontinental shipping of ...

ANGLE OF REPOSE AND ANGLE OF SLIDING FRICTION: AN EXPERIMENTAL STUDY
Geological Society of America Bulletin, 1945Earlier studies of factors determining subaerial angles of repose of loose material have produced diverse results. In order to obtain dependable information for use in geomorphic investigations a controlled experimental study was undertaken. Results show that the angle of repose varies (1) inversely with size of fragments in perfectly sorted materials,
