Pitch is used for inch gears; module for metric. Gears must have the same pitch or module in order to work together. To measure the pressure angle and pitch or module of a gear, use a Gear Tooth Pitch Identifier. If you don't have a gear tooth pitch identifier, you can estimate ...

The fact that one gear is spinning twice as fast as the other is because of the ratio between the gears — the gear ratio. In this figure, the diameter of the gear on the left is twice that of the gear on the right. The gear ratio is therefore 2:1 (pronounced "two to one"). ...
The device's diameter is larger than most of the wavelengths it produces. This allows the device to create a wavefront that's more flat than rounded, keeping the sound from dispersing. Air interferes with sound waves as they pass through it. As the LRAD's sound waves interact with the ai...

Landing Gear Another way to reduce the size of an airplane is to reduce the size of the landing gear. The landing gear on a glider typically consists of a single wheel mounted just below the cockpit. Glider Cockpit Inside a typical glider cockpit, you'll find the following: Altimeter (to...
Pitch diameter Don't forget your total thread depth axially will vary depending on the root radius. You are trying to achieve the pitch diameter. The major/minor is precut and the major/minor is a result of the pitch root radius.litle...
(Note: For the sake of graphical clarity, the drawings below do not show the penetration of the weld metal. Recognize, however, that the degree of penetration is important in determining the quality of the weld.) For plug welds, you'll see the diameter of each plug to the left of the...
Measure the diameter of the central hole in the bearing in millimeters to be sure that the bearing fits on the axle of the device you will use it with. The diameter is the width of a circle, measured on a line that passes through its center. ...
The diameter of this circle is known as the bolt circle diameter (BCD) or pitch circle diameter (PCD).Typically, BCD is quoted for chainrings on bikes and the bash guards that cover them, and you can calculate it by measuring the distance between the mounting holes of the chainring on ...
