Arm Wrestling with CAT Construction Equipment

Caterpillar (CAT), the construction equipment company, was showing off their equipment at the recent USA Science and Engineering Festival. Visitors got a look at the technology that goes into the massive equipment, including the torque sensor that tests all CAT parts. At the show, however, the sensor was set up for something else – arm wrestling.

CAT’s Uzman Hahn explains to ENGINEERING.com’s Shawn Wasserman how the sensor works.
