Analysis of Wringing Torque of Block Gauge

In wringing block gauges, one block gauge is crossed at right angles over the other and swung until the sides of both blocks become parallel. The force required for its swinging is considered to be related with wringing force and the torque of such force is termed here wringing torque.Cohesive force, tensile strength and tangential resisting force were analyzed in our previous reports, and in this report analysis is made of the fundamental characteristics of wringing torque. The findings are summarized as follows:1. It is necessary to consider wringing torque also in terms of static wringing torque and dynamic wringing torque.2. Wringing force also arises from surface tension and viscosity of oil existing between the wringing surfaces.
