WebAbstract (1) The reasons for the selection of the Goodrich flexometer for hysteresis measurements are given. (2) The machine is capable of producing results within ± 1 per cent. (3) For a given cure, the temperature rise of a stock may be increased by increasing the length of stroke, the applied load or the frequency of flexing. WebGoodrich Flexometer, a definite compressive load is applied to a test specimen through a lever system having high inertia while imposing on the specimen an additional high frequency cyclic compression of definite … is midlothian in chesterfield county
