I'm a screw-up, but she isn't.
A steel cylinder (about the thickness of a goose-quill), which forms the micrometer screw, has two threads cut upon it, one-half being cut with a thread double the pitch of the other.
And again he twisted the screw with the stripped thread, and again it turned uselessly in the same place.
They started hauling out the booze and I don't want to do anything to screw up a scholarship—especially now.
S is the head of the micrometer screw proper, s that of the screw moving the slide to which the so-called " fixed web " is attached, s' that of a screw which moves the eyepiece E.
The amount of this pressure is regulated by the screw z'.
By this screw the whole apparatus is attached to the telescope.
5) the eyepiece can be made to follow the star for a considerable distance along a position-web parallel to the screw, the bisection of the web by a star moving by the diurnal motion at right angles to the micrometer screw can only be followed for a limited distance, viz.
The later English artists have somewhat changed the mode of communicating motion to the slides, by attaching the screws pdrmanently to the micrometer head and tapping each micrometer screw into its slide.
The center passed through the axis of rotation.
8), s that of the screw which moves the eyepiece slide.
9) is only prevented by good fitting of the holes 1 3' y'; and, since the weight of the slide is on one side of the screw, misfit here will have the effect of changing the reading for coincidence of the movable with the fixed web in reverse positions of the micrometer.
It was as if the thread of the chief screw which held his life together were stripped, so that the screw could not get in or out, but went on turning uselessly in the same place.
It's stupid even fighting about any of the land before we make sure that gold-digging bitch doesn't screw us and get her hands on all of it!
