Root fracture and the design of prefabricated posts.

摘要: The derived signal is then converted to an analog for x-y recording and a digital readout. A chart recorder takes the displays it in format where ordinate torque (calibrated inch-ounces) abscissa angular rotation. developed from five-turn precision potentiometer geared output rotor of transducer (Fig. 1). Calibration system was accomplished according manufacturer’s procedure followed by application known fixed calibrated weight beam. correction +3 inch-ounces added measured readings as calibration factor. designed generate maximum 200 inch-ounces; that magnitude not exceeded during experiment.
