The Ski Gondola – Concentrated Cable Loads


 Model Description This physical model demonstrates how cables subjected to concentrated point loads establish equilibrium through geometry – i.e., the slope of each cable segment will change (as will the support reactions) as different loads are placed on the cable.  This demonstration should take 10-20 minutes. Engineering Principle Cables subjected to concentrated loads are a […]

Pulleys: The Equilibriator Challenge!


 Model Description This is a simple demonstration of the mechanical advantage associated with pulleys and a solution method for pulley problems.  By building a pulley system in the classroom, students can gain a physical appreciation for the problem at hand.  This demonstration should take 15-20 minutes. Engineering Principle This training aid demonstrates mechanical advantage obtained […]
