Abstract
A method and means for determining the amount of compressional load in an assembly of clamped elements by measuring the friction between adjacent elements in the assembly. A rotatable element is positioned between two non-rotatable elements within the assembly and the torque necessary to rotate the rotatable element is measured. By measuring or calculating the torque necessary to rotate the rotatable element with a known compressional load, the relationship between torque and compressional load can be established whereby comparison of a measured torque with the established relationship permits conversion of any measured torque to compressional load in applications where element surface coefficients of friction do not change appreciably.
