A force platform can be an excellent teaching aid in undergraduate physics classes and laboratories. Recently, Cross showed how to increase student interest and understanding of elementary mechanics by using a force platform to study everyday human movement such as walking, running, and jumping. My experiences with using a force platform in undergraduate classes have also been highly favorable....

Effects of prolonged running on Achilles tendon properties were assessed after a 60 min treadmill run and 140 min intermittent shuttle running (simulated cricket batting innings). Before and after exercise, 11 participants performed ramp-up plantar flexions to maximum-voluntary-contraction before gradual relaxation. Muscle-tendon-junction displacement was measured with ultrasonography. Tendon f...

We report a study of an elastic buckled beam undergoing contactless magnetic actuation Laplace type. The model is based on the elastica theory including extensibility. force produced by electric current travelling along placed in induction. magnitude control parameter and increasing switches from one stable state to other for given end-shortening. main purpose investigate bistable response, mor...

The mechanical state encoded by slowly adapting type 1 mechanoreceptors (SAI) during indentation was examined using an isolated preparation in a rat model. Skin and its intact innervation were harvested from the medial thigh of the rat hindlimb and placed in a dish, with the corium side down, containing synthetic interstitial fluid. The margins of the skin were coupled to an apparatus that coul...

Gait patterns, joint angles, floor reaction forces and joint moments during walking were investigated for normal subjects and above-knee and below-knee amputees. The investigation showed that the hip-knee angle diagram as well as different symmetry diagrams (e.g. left knee angle versus right knee angle) provide an easily interpreted means of evaluating abnormalities in the gait pattern. It was ...

A novel single punch tablet machine was developed for a tiny amount of powder sample. This tablet machine mainly consists of upper and lower punches, single die, and conical powder feeder equipped with micro-vibrators. By using the powder feeder, mass of discharged powder can be maintained constant even if a tiny amount of powder having poor flowability is used. Motions of both upper and lower ...

This paper describes a method by which the Kerr [1] mathematical model of a reciprocating compressor having rigid valve plates may be adapted to investigate the dynamic response of flexible valves of certain geometries. The method is restricted to flexible valves which can be modelled by spring-mass systems. Also, the section of the valve plate which is directly over the valve port must remain ...

It has been argued that the speed-density digram of pedestrian movement has an inflection point. This inflection point was found empirically in investigations of closed-loop single-file pedestrian movement. The reduced complexity of single-file movement does not only allow a higher precision for the evaluation of empirical data, but it occasionally also allows analytical considerations for mico...
