This paper presents an original interactive analysis method consisting of mathematical calculation based on theoretical mechanics and mechanics of materials, and dynamics simulation for quantifying outrigger reaction forces of a kind of hydraulic mobile crane, aiming to avoid the eventualities during normal operation as far as possible, for example, tipping-over. First, a three dimensional dyna...

Presented here is a novel technique for the in situ calibration and measurement of friction with the atomic force microscope that can be applied simultaneously with the normal force measurement. The method exploits the fact that the cantilever sits at an angle of about 10° to the horizontal, which causes the tip or probe to slide horizontally over the substrate as a normal force run is performe...

Mechanical overload due to poor conformation or shoeing has been suggested to contribute to the development of navicular disease. While studies have determined the compressive force exerted on the navicular bone in normal horses, this has not been reported for horses with navicular disease. Also, the force has not been converted to stress by correction for contact area. In this study we develop...

The purpose of this study is to explore how corn varieties and moisture content affect the mechanical properties with high (26.0~36.4%). that threshing quality are determined by establishing contact model elements kernels. These include size characteristics (corn ear weight kernel triaxial size) in addition elastic modulus, breaking force, stalk force). effects on were tested. results showed ha...

BACKGROUND Focal task specific dystonia occurs preferentially during performance of a specific task. There may be an inefficiently high grip force when doing manipulative tasks other than the trigger task, possibly reflecting a generalised impairment of sensory-motor integration. OBJECTIVE To examine how well subjects with writer's cramp (n = 4) or musician's cramp (n = 5) adapted their grip ...
