Seismic Waves. When you toss a pebble into a pond, it creates radiating waves in the water. An earthquake does the same thing with energy. When the plates fracture or slip, energy is released as seismic waves [source: USGS ]. There are several types of seismic waves. Body waves move through the inside of the Earth. There are two types of body waves: Primary waves (or P waves) are the fastest moving waves, traveling at 1 to 5 miles per second (1.6 to 8 kilometers per second). They can pass through solids, liquids and gases easily.
A #10 screw is bigger than a #8 screw and both of them are smaller than a quarter inch.0 is bigger.... the second number is threads per inch... so 10/32 or 10/24, 24 is a coarse thread and the 32 is a fine thread.... the last number is the length of the screw... 10/32 - 1 1/2 is a #10 screw with 32 threads per inch and is an inch and a half long.

Understanding Screw Sizes â Inch Standards Screws with a diameter smaller than 1/4 have a nominal size indicated by a number (e.g. #8 or #10). 1/4 and larger diameters are shown as inches.The diameter refers to the major diameter, or outside edge, of the threads.If the screw size includes a dash with a number following it, that is the number of threads per inch (tpi).Usually tpi is only shown with machine screws or other fasteners with machine screw threads.So, a 1/4-20 screw has a 1/4 diameter (.250) with 20 threads per inch./4 and larger diameters are shown as inches. The diameter refers to the major diameter, or outside edge, of the threads. If the screw size includes a dash with a number following it, that is the number of threads per inch (tpi).
