Rubber Shapes


 Model Description These physical models easily and quickly demonstrate the behavior of varying cross-sectional shapes to varying loading conditions. When the instructor passes the rubber shapes around during class, students personally experience the associated behavior and quickly catalog for themselves when shapes are best used. Applying vertical, horizontal, and circumferential lines along the length allow […]

Foam Beam


 Model Description This simple demonstration depicts how moments (and forces) result in bending of a beam and how the deformation is related to the assumptions associated with elastic beam behavior. A foam beam with vertical lines (black lines) and a horizontal line drawn along the neutral axis (red line) for a rectangular beam is used […]

Tower of Torque


 Overview Thrill your students with Tales of Torque using the versatile Tower of Torque!  In it’s simplest form, the device allows students to predict and then measure the capacity of a simple bolt, modeled as a rod in torsion. Principle For cylindrical rods in torsion, the maximum shear stress experienced is seen at the outer […]
