By limiting shell thickness (which reduces weight), smoothing the shell contours (which reduces drag), and assuming an aerofoil-like leading edge, such scallops can awkwardly swim several metres at a time.
That said, it is an adequate tool for mousing around a desktop, providing accuracy, consistency and a comfortably contoured shell that won't leave your hand feeling like a shriveled up claw.
Furthermore, in the geometrically linear analysis, the dynamic strain distribution on the top surface of the convex shell exhibited the same contour shapes as those on the bottom surface of the concave shell, with the exception of only a reversed value between the tensile and compressive strains.
The aerodynamically contoured fuselage shell characteristic of all modern aircraft was introduced at this time, and high-strength, lightweight metals (chiefly aluminum alloys, magnesium, and some stainless steel and titanium) replaced wood and fabric throughout the airframe.
The calculated contours of internal volume relative to shell thickness-namely the performance contours of the task of economy- have a curving ridge that points towards the third archetype.
The shape of the outer shell imitates the head and neck contours of an average size adult male; the maximum axial height being 255 mm, and the maximum transverse width 175 mm (Fig. 1a).
Preliminary evidence indicates that customized postural support may be warranted to optimize positioning and posture when a standard rigid shell does not align with contours of a person's back.
Because the 15% scan site has very little cortical shell, we suspected that a standard contour search would not be reliable due to the cortical shell being thinner than the 0.4 mm voxel size.
An enormous heat flux from the nozzle throat-insert inner contour conducted into the nozzle shell will degrade the material strength of nozzle shell and reduce the nozzle thrust efficiency.
The trabecular region was selected using contours inside the cortical shell on each image.
