Abstract
A variable rate test joint comprises a housing and a shaft mounted within the housing. A hexagonal head is provided for coupling a tool to be tested to the shaft. In use a frictional braking torque is applied to the shaft. A computer controls the magnitude of the braking torque applied to the shaft as a function of time.
