Theoretical study of non-Newtonian effects of second-order fluids on the performance characteristics of inclined slider bearings is presented. An approximate method is used for the solution of the highly nonlinear momentum equations for the second-order fluids. The closed form expressions for the fluid film pressure, load carrying capacity, frictional force, coefficient of friction, and centre ...

In recent years, there has been tremendous interest in employing legged and humanoid robots for dangerous missions in disaster and rescue scenarios, requiring robots to operate swiftly and stably while dealing with high levels of uncertainty and large external disturbances. One such practical example is using a legged robot to carry and manipulate large and heavy objects whose mass is not known...

Steel Plate Shear Wall (SPSW) is made from thin steel plate which in turn are framed by the beams and columns of structural system. In recent year they are proved to be very effective and economical for resisting lateral loads such as earthquake and wind loads.The present work targets to study the behaviour of single frame SPSW with different plate thicknesses, rigid and non-rigid frame members...

STUDY DESIGN An experimental approach was used to test human cadaveric cervical spine specimens. OBJECTIVE To assess the response of the cervical spine to a compressive follower load applied along a path that approximates the tangent to the curve of the cervical spine. SUMMARY OF BACKGROUND DATA The compressive load on the human cervical spine is estimated to range from 120 to 1200 N during...

The safety and operational flight envelope of helicopters carrying externally slung loads, as illustrated in Figure 1, in support of regular Army/Special Air Service (SAS) operations, is limited and sometimes seriously hindered by stability and control problems. Several incidences have been reported by the Australian Army in which possible aerodynamic excitation or dynamic instability of the sl...

this paper aims at investigating the effects of weld nugget size and expulsion on the mechanical properties of low carbon steel resistance spot welds using tensile-shear test. mechanical performance of spot welds are described in terms of failure mode, peak load and failure energy obtained from the tensile-shear test. the effects of voids and porosity as well as electrode indentation associated...

OBJECTIVE To explore the backpack load as a percentile of body weight (BW) and its impact on ventilatory function including tidal volume (Vt), vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC, peak expiratory flow (PEF), and maximum voluntary ventilation (MVV) among 9-12 year old Saudi girls. METHODS This is a prospective, experimental ...

Abstract. The modern unification of the European standards EUROCODE requires securing a constant quality of metallurgical production in the EU countries. In this paper, experimentally found statistical characteristics of yield stress, ultimate tensile strength and ductility of Czech and Austrian steel are presented. In the probabilistic reliability analysis, the experimentally found yield stres...

In driving sustainable tourism, the concept of carrying capacity in tourism needs to be applied. This gives a comprehensive emphasis development whether physical, social or economic aspects. If this is applied, it determining situation tourist destination still state that can accepted by stakeholders namely tourists, locals and tour operators. paper, given which one parts capacity. most difficu...
