Determination of the Whole Stiffness of Paper Plate

A device has been designed to measure the whole stiffness which is behalf of paper plate’s carrying capacity. When the device was working, one end of the paper plate was hold as a hand did, the other end of the paper plate was pushed to 15°angle from the horizontal surface, and the force on the paper plate was recorded. Comparing load-bearing performance, the whole stiffness is more accurate to reveal the differences of the paper plates.
