What is the common ratio of labor cost to materials during a bid?
In my opinion the ratio of labor is 40% and Material is 60%
What is the value of poisson's ratio?
Poisson ratio of most linear elastic material can be anywhere between 0 and 0.5.
What is a labor ratio and what line items belong in it?
A labor ratio is the percentage of labor spent vs the amount of revenue earned. A labor ratio is the percentage of labor spent vs the amount of revenue earned.
What is the difference between density and relative density?
Density: the ratio mass/volume for a material, expressed in kg/m3 (SI). Relative density: the ratio between the density of a material and the density of pure water at the same temperature.
Why drop of liquid acquire spherical shape?
A sphere has the most efficient ratio between the material's mass and its density.
What is typically the most efficient ratio of labor to capital?
equal amounts of labor and capital
If the speed of light in a vacuum is 1.2 times that of the speed of light in a given material what is the index of refraction for that material?
2 (no units)
Define specific gravity?
The specific gravity is the ratio between the density of a material and the density of water, at a given temperature and pressure.
Does specific gravity has units?
- The specific weight is the weight of a known volume of material at a given temperature and pressure; the unit of measure is kN/m3. - But if you think to relative density: Relative density (specific gravity) is the ratio between the density of the material to be tested and the density of water, at a given temperature and pressure; consequently no unit of measure for this ratio.
What does density signify?
The density is the ratio between the mass and volume of an material; for example the density of uranium metal is 19,05 g/cm3.
Is the mass of an object is known how much volume it has?
The volume is the ratio between the mass and the density of a specific material. V=G/d
What is the material poisson ratio of Epdm?
Depends on the hardness of the formulation. Poisson's ratio depends mainly on the bulk modulus and slightly on the Youngs modulus at very low strains for the subject compound. If the Youngs modulus lies between 0.92 and 9.40MN/m², Poisson's ratio lies between 0.49930 and 0.49993.
