Test Your BridgeProject, Tower orWood Beam MaterialWithout Destruction!

KELVIN® Continuous Pressure Analysis with Deflection (CPAD™) Test the bridge project, tower or wood beam material that you willuse for building your model bridge. The major advantage of this systemis that you do not have to break anything – just compare deflection. Deflection with the CPAD™ refers to how far the structure bendsat the given weight. For example, if you put 5 lb. of weight on a structure,one structure may bend 1” and another structure may bend more orless. With the help of the computer we can differentiate between smalldifferences in deflection which may not been seen by the eye.
