In pushing and pulling wheeled objects, the effect of the exerted force on local musculo-skeletal loads depends on the direction of force exertion. Several questions about the direction of force exertion in pushing and pulling, the effects of handle height and force level on force direction, and...
The goal was to investigate whether a simple two muscle torso model would reasonably estimate the muscle actions in pushing and pulling tasks. Six subjects participated in the experiment. EMG (rms) value was used as an indicator of muscle forces. The results show high correlation between the ...
By swiveling the caster wheels in the direction of cart travel, the pulling forces could be decreased by as much as 40%.Advances in Occupational Ergonomics and SafetyMiriam Pabon-GonzaleRobert O. Andres
Mean initial maximum acceptable forces were 439N (slip-resistant surface/pushing), 430N (slip-resistant surface/pulling), 453N (slippery surface/pushing), and 410N (slippery surface/pulling), with differences between conditions non-significant. Thus, for these subjects, maximum acceptable forces ...
aIts elegant design combines the opposing forces of pulling and pushing to support weight. Reserved for persons of high rank, folding chairs were used as portable thrones for emperors. 它典雅的设计结合敌对部队拉扯和推挤支持重量。 为高级的人预留,折叠椅使用了作为便携式的王位为皇帝。[translate]...
