External Loads on Vertically Mounted Equipment
1984Heat exchangers and pressure vessels are frequently mounted vertically to economize plant floor space. In some cases, the process function of the hardware requires vertical installation. For example, gravity driven boiling in a thermosiphon reboiler, or fractionation in a distillation column, can proceed only if the equipment is vertically installed ...

Stabilization of Externally Slung Helicopter Loads
1974Abstract : Use is made of experimental data and theoretical analyses to understand why load carrying speed is limited, and an attempt is made to identify promising stabilization concepts and to determine their capability to extend carrying speed. This effort is concentrated on the 8-by-8-by-20-foot cargo container; however, implications relating to ...

The deformation of external fixation devices during loading
International Orthopaedics, 1983The stability of four different types of external fixation devices was studied when they were subjected to torsion, bending and deformation under axial compression. The most stable fixation was achieved when the bone ends were in contact. The frames were weakest when the stress was applied at right angles to the plane of the frame.

Shoulder Joint Position Sense Improves With External Load
Journal of Motor Behavior, 2007Joint position sense (JPS) is important in the maintenance of optimal movement coordination of limb segments in functional activities. Researchers have shown that the sensitivity of musculotendinous mechanoreceptors increases as muscle activation levels increase. In the present study, when 25 participants tried to replicate the same presented position,

Three-dimensional load measurements in an external fixator
Journal of Biomechanics, 2004On the basis of a six-degree-of-freedom adjustable fracture reduction hexapod external fixator, a system which can be used for measuring axial and shear forces as well as torsion and bending moments in the fixator in vivo was developed. In a pilot study on 9 patients (7 fresh fractures and 2 osteotomies of the tibia), the load in the fixator during the

External Longitudinal Flaws in Pipes Under Complex Loading
Journal of Pressure Vessel Technology, 2000A round pipe with an external longitudinal surface flaw is assumed to be subjected to different types of elementary hoop stress distributions acting perpendicular to the crack faces. The stress intensity factors (SIFs) along the crack front for such elementary cases are determined through the three-dimensional finite element method.

External and internal air loads on sounding rockets.
Journal of Spacecraft and Rockets, 1967This paper discusses two important forms of loading experienced by sounding rockets: the running loads due to distributed aerodynamics, and loads due to aerodynamically induced pressure differentials across the skin and across internal bulkheads. An empirical method, based upon experimental data, for the rapid and accurate determination of distributed ...

Automatic External Load Acquisition by Helicopter
1974Abstract : The objectives of this study program were to establish the system requirements, to develop conceptual designs, and to analyze the feasibility of various system designs for cargo helicopters to acquire external loads without the need for manual attachment of the load to the helicopters in a loading operation.
