What is the angle of repose in agricultural engineering?

The angle of repose in agricultural engineering refers to the maximum angle at which a granular material can sit on a surface without sliding off. It specifically represents the angle measured from the horizontal at which a product, such as soil or grain, starts to move under the influence of gravity. This concept is critical in fields such as material handling and soil mechanics, where understanding the stability of piles, slopes, or beds of agricultural products is essential for safe and effective operations.

In agricultural applications, knowing the angle of repose helps engineers design structures such as silos, storage facilities, and hoppers, ensuring that materials do not overflow or cause blockages during transportation. Understanding this angle also plays a key role in determining how materials behave in different environments, which is vital for planning and managing agricultural systems effectively.
