Screw Gauge is a mechanical tool which facilitates measuring diameter or radius or thickness of a thin wire or thickness of thin metal sheet with utmost accuracy.
What are screw gauges used for?
The screw gauge is an instrument used for measuring exactly the diameter of a thin wire or the width of a sheet of metal.
What do you know about pitch of screw gauge?
Pitch of the screw gauge is equal to the distance moved by the screw is divided by the numbers of full rotations given. Therefore the pitch of a screw gauge is the angular distance covered in one rotation of screw.
What are the two uses of screw gauge?
Screw gauge, is a device incorporating a calibrated screw used widely for precise measurement of small distances in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers.
Who made screw gauge?
The first model of the screw gauge was designed by William Gascoigne in the 17th century by making some modifications to a vernier caliper in order to use it in a telescope to measure the angular distances between stars and other celestial bodies.
What are the parts of screw gauge?
A screw gauge consists of a “U” shaped metallic structure, which is attached to a hollow cylindrical tube on one end. The hollow tube has a uniformly threaded nut inside it.
Thus the main parts of a micrometer screw gauge are:
What is the other name of screw gauge?
A micrometer, sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw widely used for accurate measurement of components in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers.
What is the mechanical advantage of screw gauge?
The mechanical advantage of using a screw involves the spreading of the effort over a longer distance thereby allowing heavy loads to be overcome with a smaller amount of effort. This means if you can twist your screwdriver with a force of IN you can generate a force of 4N.
What is the construction of screw gauge?
The Screw Gauge consists of aU shaped metal frame. A hollow cylinder is attached to one end of the frame. Grooves are cut on the inner surface of the cylinder through which a screw passes. On the cylinder parallel to the axis of the screw a scale is graduated in millimeter called Pitch Scale.
