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.

Thus, a 10 gauge steel sheet which has a thickness of 0.1345 inches will weigh 41.82*0.1345 = 5.625 pounds per square foot. Examples: 16 ga CRS is 2.5 pounds per square foot. For 18 ga CRS the weight is 2.0 pounds per square foot and for 20 ga CRS the weight is 1.5 pounds per square foot.
