Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.
It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa ⋅ m 3 / kg , or N ⋅m/kg, which is dimensionally equivalent to m 2 /s 2 , though the latter form is rarely used.
A reducer reduces the pipe size from a larger to a smaller bore (inner diameter). Alternatively, reducer may refer to any fitting which causes a change in pipe diameter. [15] This change may be intended to meet hydraulic flow requirements of the system or adapt to existing piping of a different size. The reduction length is usually equal to the ...
In most cases, joint clearances of 0.03 to 0.08 mm (0.0012 to 0.0031 in) are recommended for the best capillary action and joint strength; [6] in some brazing operations, however, it is not uncommon to have joint clearances around 0.6 mm (0.024 in). Cleanliness of the brazing surfaces is also important, as any contamination can cause poor ...
Safety wire is commonly 0.5, 0.6, 0.8 or 1 mm (0.020, 0.025, 0.032 or 0.041 in) in diameter, but 0.5-and-1 mm (0.021-and-0.051 in) diameters are also available. It is usually made of stainless steel, but is also available in monel and inconel alloys for high temperature applications and copper for break-away applications. [7]
A draft of 2 to 3° is required. Wall thicknesses are limited to 3 to 50 mm (0.12 to 1.97 in). Typical part sizes range from 100 g to 75 kg (several ounces to 150 lb). Other advantages include the ease of inducing directional solidification by changing the mold wall thickness or by heating or cooling portions of the mold.
The 30-06 Springfield cartridge (pronounced “thirty-ought-six”, "thirty-oh-six") or 7.62×63mm in metric notation, was introduced to the United States Army in 1906 (hence “06”) where it was in use until the late 1970s. It remains a very popular sporting round, with ammunition produced by all major manufacturers.
It is valued for its strength to weight ratio. [citation needed] The "HY" steels are designed to possess a high yield strength (strength in resisting permanent plastic deformation). HY-80 is accompanied by HY-100 and HY-130 with each of the 80, 100 and 130 referring to their yield strength in ksi (80,000 psi, 100,000 psi and 130,000 psi). HY-80 ...
