These systems are used for measuring the thickness of films or other semiconductor materials. The measurement is taken using light reflections and a computer to process and display the reading. The thickness measurement range is from 1 nm to 1 mm. These systems are usually used in scientific lab...
Select a cylinder that is large enough to hold the volume of liquid being measured. Confirm that the tube is clean and dry. Unwanted particles or drops of liquid in the cylinder could throw off the measurement. Steady the tube with one hand while pouring the liquid you are measuring into i...
Plasitgauge is a proprietary system for measuring clearances between fitted surfaces of machine parts, such as crankshaft or camshaft bearings. Made from a special extruded plastic thread with accurately controlled crush properties, Plastigage provides a fast and accurate way to check bearing clearances...
The knee is a massive casting that rides vertically on the milling machine column and can be clamped rigidly to the column in a position where the milling head and milling machine spindle are properly adjusted vertically for operation. The plain vertical machines are characterized by a spindle l...
More than 100 years ago the Wright brothers made their historic first flight in Kitty Hawk, N.C. Even after all these years, their creation still boggles the mind: How can something so heavy take to the air?

When pouring to a line on a graduated measure the meniscus should be a continuation of that line. Misjudging the effect of the meniscus could result in an over pour. Whatever jigger or measuring vessel you use the objective is to end up with the ratio of each ingredient to the other as ...
used to lift automobiles, houses, and other heavy objects is an application of this principle. The internal screw is situated in the base, the external screw on a metal cylinder; at the top of the cylinder a lever or handle is fastened. As the handle is rotated, the external screw moves...
