1. A tensile impact apparatus comprising:
a slider bar having an impact surface and capable of sliding on a support member;
a first guided base retained on a support rail and capable of linear movement thereon, said first guided base communicating with a first grip through a first load cell;
a second guided base retained on a support rail and capable of linear movement thereon, said second guided base communicating with a second grip through a second load cell, said first and second grips being substantially aligned for linear movement towards or away from each other and further being adapted for gripping opposed ends of a rubber sample;
a first cable connected between said slider bar and said first guided base;
a second cable connected between said slider bar and said first guided base;
a first displacement transducer associated with said first guided base;
a second displacement transducer associated with said second guided base; and
a pendulum adapted for striking said slider bar such that, when said pendulum strikes said slider bar, said slider bar slides on its associated support member and pulls said first and second cables such that said first and second guided bases are substantially simultaneously moved away from each other by the pulling force of their respective first and second cables, and said first and second grips are also substantially simultaneously moved away from each other due to their respective communication with said first and second bases through said first and second load cells.
