1. A shock testing machine comprising:
a base;
one or more rails supported by the base and extending in a testing direction;
a test platform for holding an item to be shock tested;
a carriage for carrying the test platform and being movable relative to the test platform along the one or more rails in the testing direction, the testing direction being a direction of movement of the carriage along the one or more rails;
a stop fixed to the base at a predetermined location, the stop being configured to directly engage with only the carriage to stop a movement of the carriage in the testing direction at the predetermined location while allowing the test platform to separate from the carriage in the testing direction and continue moving in the testing direction past the predetermined location; and
a brake configured to decelerate the test platform after the test platform has been separated from the carriage by the stop,
wherein the brake comprises one or more elongated members extending from the test platform in a braking direction opposite to the testing direction, the one or more elongated members being engageable with braking material disposed on the carriage such that when the carriage stops moving in the testing direction at the predetermined location and the test platform continues moving in the testing direction past the predetermined location, the at least one elongated member engages with the braking material to decelerate the testing platform.
