释义 | cantilever noun[ C ] engineering specializeduk /ˈkæn.tə.liː.vər/ us /ˈkæn.t̬ə.liː.vɚ/ a long bar that is fixed at only one end to a vertical support and is used to hold a structure such as an arch, bridge, or shelf in position: (支撑桥梁等的)悬臂梁,肱梁 a cantilever bridge悬臂桥 Chris Hepburn/robertharding/GettyImages Physical supports and supporting abutment bearing bolster bookend buoy burden buttress groan modillion pier pile pillar prop prop something up rafter runner scaffold sinew underpin weight-bearing Examples of cantilevercantilever By following the cantilever displacements as the cells migrated over these cantilevers, they determined the distribution of tension exerted by the cells on the substrate. A laser beam is directed at the reflective, upper surface of the cantilever, and the deflected light detected by a four-quadrant photo-detector. The motion is monitored now by a laser beam, which is reflected onto a split diode from the cantilever holding the sensor tip. The position of the cantilever is monitored by the deflection of a detecting laser. Large deformations of cantilever beams, that are subject to distributed loadings can be solved by using pseudolinear equivalent systems. The spatial mode function can be selected freely using, for example, a cantilever mode8 (clamped-free) function as is done in this work. During a third mode of operation, 'force-distance measurement', the cantilever is slowly lowered towards the surface and its deflection is constantly recorded. Its main deformation was a bending vibration similar to the third mode of a cantilever beam. The structure of firewalls, circulation spine, and cantilevered floors leaves the east and west elevations free of load-bearing requirements. It is a concrete skeleton with a central spine, cantilevering off which are concrete slabs - floors and services and ceilings. Structural steel beams, for instance, have been introduced to minimize the deflection in horizontal slabs, bridging very large spans or projecting in large cantilevers. Pads of 4-25 m# are positioned on the ends of the cantilevers. The extension of the molecule is determined from the relative positions of the end of the cantilever and the translational stage. Meanwhile, the pull-out speeds and cantilever mechanics must be carefully considered when 'absolute' force values are cited. And then the canopy, high enough to accommodate moderately tall vehicles, steel framed with big cantilevers and supported by columns standing on the pump islands.
