Problem Statement

This project entails the design, analysis, and construction process of battery operated extendable limb shears. The design consists of shears mounted on top of extendable poles and is powered by a DeWalt hand-held drill mounted on a manufactured steel box. By using the mechanics of pulleys and tension force, the shears can cut branches up to 1.5 inches in diameter and as tall as 16 feet above the ground.
