Since 1905, the Department of Agricultural Engineering, now the Department of Agricultural and Biosystems Engineering (ABE), has been a leader in providing engineering solutions to agricultural problems in the United States and the world. The department’s original mission was to mechanize agriculture. That mission has evolved to encompass a global view of the entire food production system–the wise management of natural resources in the production, processing, storage, handling, and use of food fiber and other biological products.
History
In 1905 Agricultural Engineering was recognized as a subdivision of the Department of Agronomy, and in 1907 it was recognized as a unique department. It was renamed the Department of Agricultural and Biosystems Engineering in 1990. The department merged with the Department of Industrial Education and Technology in 2004.

Abstract
Flat-bottom cylindrical grain bins are subjected to unique loads and pressures during the filling process. The vertical and lateral loads imposed on a bin wall and the vertical load on a bin floor by wheat during filling were measured. The radial distribution of vertical pressure during filling was also measured. The vertical pressure was determined to be dependent on the radial location and was not uniformly distributed. The load distribution in a bin with an H/D ratio of 3 was 83% on the floor and 17% on the walls. Three widely used prediction equations of Janssen, Reimbert, and Walker were compared to the measured loads and pressures and were determined to have similar shapes but different parameters for a best fit to observed data.
