1R40.10 |
[:MEEquipmentList:Bouncing Ball] |
Drop balls of different material on to a tool steel plate. Loss of mechanical energy in the coefficient of restitution. Drop balls on a glass plate. Balls of various materials are bounced off plates of various materials. |
1R40.10 |
Coefficient of Restitution |
Drop glass, steel, rubber, brass, and lead balls onto a steel plate. |
1R40.11 |
Coefficient of Restitution |
Drop a small ball bearing on a concave lens. |
1R40.12 |
Coefficient of Restitution |
Rubber balls of differing elasticity and silly putty are dropped in a tube onto a steel surface. |
1R40.13 |
Coeffficient of restitution in Baseballs |
Analysis leading to a prediction of up to 15 foot difference in long fly balls due to variation in coefficient of restitution. |
