Angle of Repose and Other Handling Angles

The angle of repose is defined as the angle of the free surface of a pile of powder to the horizontal plane. Depending on the conditions under which the pile has been poured and how the 

There are two main definitions of the angle of repose as follows. 

The POURED ANGLE of repose is the angle measured on a pile poured freely onto a flat surface while 

As to the actual procedure and type of angle adopted, it clearly depends on the application in question and the conditions it serves to simulate. 

Carr describes36 an angle-of-repose plate which incorporates a protractor, indicator wire and a jarring device (the jarring device is used to measure the angle of fall, see below).
