A method for assessing the state of hair by releasably engaging a first end of hair fibers with a holder which so that an opposite, second end of said hair fibers hangs free and applying sufficient force to the second end of the hair fibers such that the hair fibers at the first end are pulled from the holder.

A method for creating a composite cable having at least one advanced termination on at least one end. An advanced termination is added to an end of a short synthetic tensile strength member. The strength of the tensile strength member and termination is then tested. Once tested satisfactorily, the short cable is spiced onto a long cable of the same type using prior art splicing techniques. The union of the short cable and the long cable creates a “composite” cable having a advanced termination on at least one end. In most applications it is preferable to set the length of the short cable so that the interwoven splice will exist at a desired location.

A method and an apparatus for examining the fracture strength of flat samples made of brittle-fracture material are provided. The margin of the respective sample is subjected to tensile stress by bending the material in a circular arc shape.

A torsional fatigue testing apparatus comprises: a cable holding device, a motion guiding device and a driving device. The cable holding device is provided for holding a cable to be tested to extend between a rotatable holder and a slidable holder. The motion guiding device is provided for converting the rotational motion of the driving device into a reciprocating linear sliding motion by means of linkage so as to alternately rotate the rotatable holder forwardly and reversely, and therefore to repeatedly twist, by the rotatable holder, the cable to be tested.

A hose to be evaluated is installed on a fixing frame in a preset shape, and a strain gauge and markers are attached to a surface of the hose. During a course of application of predetermined internal pressure to the hose, strain data is acquired using the strain gauge and an image of an external shape of the hose is captured using a camera device to acquire image data. Based on the strain data and the image data acquired, a change in the shape of the hose between a plurality of time points at identical internal pressure is determined. Such hose fatigue resistance evaluation system can determine changes in the degree of deformation of a hose over time due to repeated application of internal pressure.

A device and method for testing the working performance of an anchor rod cable by simulating stratum fracture and separation on the basis of electromagnetic action, applicable to the technical field of testing working performance of anchor rod cables by simulating a tunnel field.
