The present large sample of undergraduates (N = 1412), majoring in natural and applied sciences, and social sciences or humanities and arts, completed water-level and plumb-line items, along with other simple physics problems, indicating how and in reference to which principle they had solved ...
A projected light image, such as a laser line segment of relatively short length may be successively stepped across a long wall while maintaining its level or plumb condition. A low powered laser or other light source may be used to generate the short-length, line segment in place of a ...

As true as it is that a bricklayer needs a plumb line and a T-square, so it is that a physicist using general relativity needs how to draw geodesics and use fields of congruent vector frames of reference. While the first part of the prec... L Bel 被引量: 0发表: 2008年 Multiple sh...
(Supplementary Fig.4), creating a plumb-line-shape-like response of spin configuration to the flexo-bending deformation. This tendency is more prominent on the edge atoms and enhanced with the increase in curvature, thus inducing the transition from a pristine collinear state (radial state) to ...
line of the swing. Additionally, present putter head designs provide a head striking surface that has a vertical height above the ground only slightly above the height of the forward circumferential contact point on the ball (0.84 inches high). Therefore, striking the ball in the center “sweet...
FIELD: physics.;SUBSTANCE: coordinate scale of the string of an inverted plumb line has a toroidal-shaped vessel containing liquid, a float, a position-sensitive satellite-borne receiver, a tribach and a computer. The coordinate scale also has a measuring mark attached to the sting of the ...
A tool (10) for use in establishing a precise level line or plumbine or line for alignment uses a visible laser diode (24) for projecting the line. The tool is relatively small and compact, drives the laser diode (24) using batteries (22) contained in the tool (10), and includes ...
FIELD: physics, measurements.;SUBSTANCE: invention relates to sea geodesy and can be used to define deviation of plumb-line (DPL) in ocean on a mobile object for navigation-hydrographic maintenance of its navigation complex. In compliance with the proposed method, four gravimetric devices are used...
