Dynamometer, 1934

A tractor driver and Iowa State Professor J.B. Davidson looking at an Iowa integrating and recording traction dynamometer, mounted on the linkage between the tractor and the piece of farm machinery being pulled. The farm tractor has rubber tires. The machinery has iron wheels.

The history of the College of Agriculture and Life Sciences begins with the founding of the Iowa Agricultural College and Model Farm in 1858, with classes beginning in 1869. As a land-grant institution, Iowa State was founded primarily to provide practical education in agriculture and the mechanic arts. Through the years, agriculture courses and short courses have focused on agricultural engineering, agronomy, animal husbandry, dairying, forestry, and horticulture. In the 21st century, the focus is on animal and the plant sciences, biotechnology life sciences, sustainability, and global development.
