Crane Rigging Angles


 Model Description This demonstration depicts the importance of rigging angles during crane lift operations on a construction site.  Reducing rigging angles results in a significant amplification of forces in the rigging, potentially leading to failure.  By varying the connection points and sling length, students will be able to calculate the predicted forces and analyze the […]

The Persuader


 Model Description Use this daunting looking model to set the stage for a lesson on 3-D equilibrium and eventually persuade your students that it’s easier than it looks!  This demonstration should take 20 minutes. Engineering Principle 3-D equilibrium for a non-concurrent force system requires the simultaneous solution of six equations of equilibrium, three equations for […]
