Ensemble Force Spectroscopy by Shear Forces
Journal of Visualized Experiments, 2022Single-molecule techniques based on fluorescence and mechanochemical principles provide superior sensitivity in biological sensing. However, due to the lack of high throughput capabilities, the application of these techniques is limited in biophysics. Ensemble force spectroscopy (EFS) has demonstrated high throughput in the investigation of a massive ...

Proximal electromagnetic shear forces
Journal of Microscopy, 1999We perform a simple model calculation to estimate the electromagnetically induced shear force caused by a current dissipation when a charged tip is moved parallel to a conducting material. For parameters typical in shear force imaging, the force is many orders of magnitude below reported values.

Tuning fork shear-force feedback
Ultramicroscopy, 1998Investigations have been performed on the dynamics of a distance regulation system based on an oscillating probe at resonance. This was examined at a tuning fork shear-force feedback system, which is used as a distance control mechanism in near-field scanning optical microscopy.

Indirect shear force estimation for multi-point shear force operations
Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, 2013The possibility of using shear forces is being explored recently as a method to enrich touch screen interaction. However, most of the related studies are restricted to the case of single-point shear forces, possibly owing to the difficulty of independently sensing shear forces at multiple touch points.

Interfacial shear force microscopy
Physical Review B, 2000We present an experimental investigation of lossy and reactive shear forces at the nanometer scale using quartz-crystal tuning-fork shear-force microscopy. We show that this technique allows us not only to quantitatively measure viscous friction and elastic shear stress with a combination of high spatial and force resolution (better than 10 nm, and ...

Shearing Forces and Bending Moments
1990In the previous programme we studied the effect of external loads upon the members of pin jointed frames. We saw that, as a result of the loading, such members were subjected to direct forces acting along their longitudinal axes and increased or decreased in length according to the sense of those forces.

Nuclear Physics B - Proceedings Supplements, 1987
Abstract Slight amounts of forcing have traditionally been used in fluid-mechanic stability experiments. It was usually assumed that forcing provided a regular disturbance above the background noise--making the subsequent development easier to follow--but did not otherwise alter the physical process.

Shear Forces in Molecularly Thin Films
Science, 1989Monte Carlo and molecular dynamics methods have been used to study the shearing behavior of an atomic fluid between two plane-parallel solid surfaces having the face-centered cubic (100) structure. A distorted, face-centered cubic solid can form epitaxially between surfaces that are separated by distances of one to five atomic diameters.

Industrial Test on Shearing Force of Rolling Shear
Advanced Materials Research, 2010The accuracy of the max shear force of rolling shear is of vital importance to the proper selection of motor power and the optimization design of structure strength. The test on shear force during the shearing process of stainless steel was done on 3000 mm cut-to-length rolling shear of some Large-scale Iron & Steel Co., Ltd.
