Erie Canal Technology: Stump Pullers
Greenslade, Thomas B., Jr.
Physics Teacher, v51 n7 p437 Oct 2013
Many years ago I saw a picture of a huge set of wheels that was used to remove tree stumps during the construction of the Erie Canal (1817-1825) and was intrigued by its use of leverage, mechanical advantage, and torque. Figure 1 is a scale model of the device based on my memory of the (lost) picture and published accounts.
