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.

The 8 refers to the size (diameter) of the screw, and the 32 means it has 32 threads to the inch. Most of the screws for mounting hinges are self-tapping (they tap their own mating threads in wood) type AB (they have more threads per inch and are more effective in brittle materials like wood than Type A).owever, most wood screws do not include the threads per inch measurement and would just be listed as 8 X 1. If the gauge number is not known, simply measure the diameter of the shank in inches and round to nearest listed number on chart below for screw number identification.
