(PhysOrg.com) -- Scientists know that cancerous cells and normal cells have different physical features, but the details of these differences, and why they occur, are not well understood. In a recent edition of Nature Nanotechnology, ...
(PhysOrg.com) -- Devices that harvest ambient energy from the surrounding environment have become popular since, for some applications, they eliminate the need for batteries that must constantly be replaced. One of the most ...
(PhysOrg.com) -- By using light to change the elasticity of a DNA molecule, scientists have designed a molecular motor that can turn light into mechanical work. Unlike most previously reported molecular motors, the proposed ...
Looking for life on other planets is not straightforward. It usually relies on chemical detection, which might be limited or even completely irrelevant to alien biology. On the other hand, motion is a trait of all life, and ...

(PhysOrg.com) -- For a long time, scientists have been trying to transform the collective movements of tiny molecules into useful mechanical work. With this goal in mind, a team of researchers from Japan has developed a crystal ...
(PhysOrg.com) -- Working together, Matthieu Gaudet and Steve Arscott from the University of Lille (IEMN lab) in France have built a circuit using a phenomenon known as photoelectrowetting, which allows a switch to be turned ...
(PhysOrg.com) -- By taking advantage of the vagaries of the natural world, Duke University engineers have developed a novel approach that they believe can more efficiently harvest electricity from the motions of everyday ...

A cantilever is a beam anchored at only one end. The beam carries the load to the support where it is resisted by moment and shear stress. Cantilever construction allows for overhanging structures without external bracing. Cantilevers can also be constructed with trusses or slabs.
This is in contrast to a simply supported beam such as those found in a post and lintel system. A simply supported beam is supported at both ends with loads applied between the supports.
