K’NEX Trusses


 Model Description This simple pair of K’NEX models can demonstrate how trusses greatly increase the strength/stiffness of structures without adding much weight. The trusses are built out of K’NEX pieces and topped with construction paper to produce a roadway. Text books are used to load the trusses to demonstrate its strength to weight ratio.  This […]

Particle Equilibrium Demonstrator


 Overview Understanding the concept of particle equilibrium is critical for success in the mechanics curriculum. The equilibrium demonstrator described here helps students to grasp this concept as well and provide a means of visualizing vector components in two or three dimensions Principle The primary principle relevant in this example is Newton’s first law of motion, […]
