The shapes of two wires in a vertical plane with the same starting and ending points are described as complementary curves of descent if beads frictionlessly slide down both of them in the same time, starting from rest. Every analytic curve has a unique complement, except for a cycloid (solution of the brachistochrone problem), which is self complementary. A striking example is a straight wire ...

rolling-based seismic isolation systems, in which rollers of circular or non-circular section are used, are less expensive and easier to manufacture. however, this type of isolation suffers from either lack of restoring or re-centering capability, or weakness against uplift forces. to resolve the first shortcoming the use of elliptical as well as pillow-shape rolling parts has been suggested, a...
A series of cyclic tension-torsion tests under symmetric shear strain and asymmetric axial stress control in various loading paths are conducted on 100 μm-diameter 316L steel wires applying a micro tensiontorsion fatigue testing apparatus. The ratcheting strain of the thin wire increases with increasing axial mean stress and decreases in a sequence of linear, rhombic and circular paths. The mac...
The paper presents the results of studies structure and properties a wire with diameter 0.5 mm from an alloy Al-REM system rare-earth metal content 7–9%. Wire obtained as result implementation technology its manufacture using methods casting into electromagnetic mold (EMM), continuous extruding, drawing. rheological continuously cast round billets experimental are determined. modeling analytica...
The purpose of this study was to investigate the acute effects of foam rolling on quadriceps isokinetic and isometric force production as well as knee joint range of motion. Twelve healthy, light to moderately physically active college students volunteered for this study. They had different treatments on three separate days. Participants' non-dominant knee joint range of motion (ROM), quadricep...
