Perpendicular to the direction of orbital motion of the earth around the sun, the trace length would then be
But there are ways to detect the Moon's orbital motion directly in the course of just an hour or less.
Nevertheless, during this phase, orbital motion would result in more heating than linear motion, and therefore it will also result in more squeeze flow than linear motion.
The bearing consists of two parallel plates where one is fixed while the other plate undergoes an orbital motion. These bearings operate under high speed and high load conditions.
In the thrust slide bearing, when an oil particle becomes trapped in the sliding space, it can, in theory, never escape due to the moving scroll's orbital motion. The trapped oil particle is then heated by the shear stress.
On sufficiently long timescales, the apparently regular orbital motion of many bodies in the solar system can exhibit symptoms of this chaotic behavior.
These include hipster, modernist-inspired fare, such as the Glam chandelier for $198, the Cubist platter for $38 and the Atomic fruit bowl with a design that "captures the orbital motion of atomic particles" for $42.
Also orbital vibration welding, a friction process that uses constant-velocity orbital motion to weld materials with as as 30-mil part-to-part clearance; hot-plate welding, a direct thermal welding technique suitable for complex, irregular shapes (joint can be curved in all planes); spin welding suitable for circular parts with final orientation within 1[degrees], and thermal welding.
Orbital motion also allows the tool diameter to be smaller than the hole, which makes for efficient chip and heat extraction.
Consequently, the "U"-shaped inductor, as well as other massive components (including output transformer of power supply, water cooled coil, busswork, cables, etc.) that often weight more than 2,000 lb., must travel with the orbital motion of the connecting-rod journals.
