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.

Centrifuges and inertial shear forces.
Journal of gravitational physiology : a journal of the International Society for Gravitational Physiology, 2004Centrifuges are often used in biological studies for 1 x g control samples in space flight microgravity experiments as well as in ground based research. Using centrifugation as a tool to generate an Earth like acceleration introduces unwanted inertial shear forces to the sample.

In-shoe biaxial shear force measurement: The Kent shear system
Medical & Biological Engineering & Computing, 1996The Kent shear system is introduced and preliminary clinical results are presented. A technique utilising copolymer piezoelectric film has allowed the manufacture of biaxial in-shoe transducers capable of simultaneously measuring two orthogonal shear forces. Bipedal measurements are carried out inside everyday footwear over multiple footsteps.

Microfluidic Shear Force Assay to Determine Cell Adhesion Forces
2019Cell adhesion is implicated in many physiological settings such as the retention of hematopoietic stem cells (HSCs) in their bone marrow niches or their migration into the bloodstream. During HSC mobilization these adhesion sites are cleaved and have to be newly formed during HSC homing and engraftment.

Beams Under Transverse Shear Forces
2021In the previous Chap. 5 we have dealt with straight beams under normal force and bending moments and mainly dealt with the determination of the normal stress \( \sigma _{xx} \) as a result of the normal force N and the two bending moments \( M_y \).
