The screw has helical ribs on a core which has axial sections of different radii of curvature. The sections are even in number, at least four, and alternate between a radius of curvature up to 15% smaller and a radius of double that of the inside cylinder wall or more. The wedge-...
Why the focal length of a spherical mirror has a smaller magnitude than that of its radius of curvature?Focal Length:In optics, focal length represents the distance between the centre of the mirror or lens (which is also known as a pole) and the focal p...
We also found that the most preferred radius differed among strains. Notably, the preference was independent of the volume of substrates, suggesting that D. suzukii uses the surface curvature as a cue for its oviposition site selection. These results provide an additional explanation for why D. ...

The force due the Laplace pressure acting on an the top face of a pillar can be calculated from f = 2γLπR2/rd, where rd is the radius of curvature of the drop. Since R/rd ≪ 1 we neglect it. See [38] for a correction calculated with the full Laplace equation. We take ...

The system has a bevel flank (20) and a crown gear flank (21), whose micro-geometries are modified in such a manner that a gap curvature on a side turned toward the progressive movement becomes smaller, during rolling in a main movement direction. The modification is produced by a modified...
Verification of the Effect of Design Parameters on the Radius of Curvature of Vine-Like, Power Soft Gripper We are developing a vine-Like, power soft gripper based on Euler’s belt theory to achieve high load capacity for grasping irregularly shaped heavy o... Hiroto Kodama,Hiroyuki Nabae,Gen...
SOLUTION: This refractory coating structure 1 of the arc tunnel is characterized in that a flat bar 3 formed by curved at a curvature radius smaller than the curvature radius of the tunnel inner wall 2a is disposed in the arc tunnel 2 with it extended in the tunnel circumferential direction,...
Refrigeration condense for rear wall mounting on cabinet has smaller radius of curvature between parallel sections to reduce sizeThe serpentine condenser tubing (3) is formed with parallel sections (9) attached to sheet or wire heat dissipators to liquify the refrigerant gases. The radius (6) ...
