FIELD: measurement of limiting stress of section ( tangential stress ) of various solid-like materials, specifically, hard cheeses. SUBSTANCE: displacement meter includes case with central bushing loaded with spring, riffled cylinder fixed in central bushing on which disc is put, pointer anchored on disc opposite to scale set on case. Drill bit is mounted inside and coaxially to cylinder, its lower end carries spiral-shaped cutting tools with outer diameter less than diameter of hollows of riffled cylinder fixed at equal pitch along circumference. Their shape corresponds to angle of internal chamfer of cylinder. Lower end of drill bit bar is fitted with conical tip with spiral thread and upper end of it is equipped with handle. In addition disc of central bushing contacts spring-loaded cam of brake. EFFECT: increased accuracy and simplification of measurement process. 5 dwg
