ABSTRACT:
Method of precisely positioning a first terminal portion of an elongated tensile rod with respect to a base member coupled to a second terminal portion of the tensile rod which has a threaded portion, involves providing an electrical strain gage measurement device affixed to the tensile rod, a load tube positioned about the rod, having a first terminal portion positioned against the base member, and tightening a nut member over the threaded portion of the rod and against the load tube for producing compression of the tube and tension within the rod until a signal produced by the strain gage measuring device indicates a desired position of a terminal portion of the rod with respect to the base member.
