Abstract

The rebound velocities of freely dropped steel bars on a large external surfaces were investigated. A high speed video system was used to capture the kinematic data. The number of contacts and the contact time were determined by using an electrical circuit and an oscilloscope. Six bar lengths were used at various pre impact inclinations and velocities of the bars. Internal vibrations of the bar and multi impacts between the bar and the surface were found to be the factors that cause the variation of the coefficient restitution. A slenderness factor was proposed to identify the subject of collision problems where the coefficient of restitution was invariant to the inclination angle. The applicability of Coulomb's law of friction was verified.
