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 […]

Engine Knock


 Model Description This is a training aid that can be used during the discussion of engine knock in internal combustion engines, and to show the severe damage it can cause to engine components.  This demonstration should take 5-8 minutes. Engineering Principle Engine knock, or autoignition is the premature ignition of the fuel-air mixture in a […]

Wacky Fun Noodle


 Model Description This is a simple demonstration to show how tension and compression affect members of trusses. A wacky fun noodle (tube floatation device) will be used to demonstrate the effects of tension and compression on axial members. Students pull or push each end to display the desired behavior.  This demonstration should take 5-10 minutes. […]
