Abstract
PURPOSE: To improve test accuracy by disposing a load display plate on the turning locus of an arm and having displaying done on the load display body.
CONSTITUTION: A tensile stress measureing apparatus 2 consists of an electromagnetic coil 5, a suction plate 6, a spring 7 for detaching this suction plate 6, a pen holder 8 fitted to the suction plate 6 and a pen 9 for displaying load on a load display plate 90. While the measuring person is measuring the distance between the gauge marks inscribed on a test specimen 13 with a scale, he operates a pedal type switch 4 when the percentage of elongation reaches 100%, 200% or 300%. This causes the suction plate 6 to be sucked to the electromagnetic coil 5. Since the pen 9 is fitted to the suction plate 6 via the penholder 8, the suction of the suction plate 6 causes various tensile stress loads to be displaced momentarily on the load display plate 90 by the pen 9.
