Measuring Pile Deflections with Inclinometer

Journal of the Geotechnical Engineering Division, 1974
As part of an extensive study of the resistance to lateral loads of piles in pile groups, a series of full-scale tests was conducted. The selected test site was representative of field conditions that the Pennsylvania Department of Transportation encountered during design/construction of bridges.

The measurement of sub-brownian lever deflections

IEEE Symposium Conference Record Nuclear Science 2004., 2005
A micromechanical lever that deflects in response to the impacts of charged particles has previously been proposed as a means of improving upon the capabilities of existing radiation detection technology. The momentum detector offers promise as a highly discriminating, high-resolution tool for ion sensing.

Structural deflection measurement

The Journal of Strain Analysis for Engineering Design, 2003
The concept of measuring deflection curvature of structures under bending loading with a device called a ‘curvature gauge’ is described. The application domain is specified in which this concept offers advantages over the alternative of measuring strain in terms of the measurement sensitivity, flexibility to choose the location for the sensor placement

Principles of deflection-curvature measurement

Measurement Science and Technology, 2001
As an alternative to strain measurement, a sensor of structural deflection curvature has been reported by the present authors. The operation of this `curvature gauge' is now explained and computer simulated in order to improve its performance and visualize the effects within its optical fibre, that curves together with the supporting structure under ...

Optical deflection measuring system

Precision Engineering, 2007
Abstract A system for accurate real-time measurement of deflections was developed. A stable laser source is, by means of a single-mode fiber, coupled to an optical head located at one end of deformed structure. A detector circuit with a quadrant detector and processing electronics, located at the other end of the structure, communicates the resolved ...

Deflection Measurements with Weak Values

Frontiers in Optics 2010/Laser Science XXVI, 2010
We report an interferometric weak-value technique to amplify transverse beam deflections. The utility is quantified through an investigation of the signal to noise ratio along with the experimental results.

Photothermal beam deflection measurements on agricultural produce

Journal of Food Engineering, 1996
The technique of photothermal beam deflection has been used to determine the thermal diffusivity of beans with varying levels of hydration. A strong relationship between the water content and measured thermal diffusivity was observed. The technique was also tried on other kinds of agricultural produce but was found to be unsuitable for non-destructive ...

Measurement of badminton racket deflection during a stroke

Sports Engineering, 2010
The compliance of a badminton racket is an important design consideration, which can be better understood by studying the deflection behaviour of the racket during a stroke. Deflection can be measured using direct methods, such as motion capture or high speed video, or by indirect methods, which then require a mathematical model in order to calculate ...

Speckle-Based Deflection Techniques in Diffusivity Measurements

Defect and Diffusion Forum, 2011
Optical techniques have a long tradition in flow visualization, allowing both qualitative and quantitative analysis. In particular, speckle photography, introduced in 1968, has been extensively used. The aim of this work is to discuss speckle-based deflection techniques in the investigation of diffusion phenomena in liquids.
