Is there a formula to calculate metal strength by thickness?
Yes - there are many different formulae but the relationship of hardness to tensile or yield strength is at best very approximate. There is a general increase in hardness with increasing strength for most metals - where hardness has been measured by an indentation method such as Brinell.
Do types define a set of values and a set of operations that can be applied on the values?
Yes.

Why is hardness a valuable property of some minerals?
Hardness is valuable because it helps in mineral identification by determining resistance to scratching. Minerals with higher hardness values can scratch minerals with lower hardness values, aiding in their classification. Hardness also indicates the strength and durability of a mineral, making it useful for industrial and practical applications.
What hardness testing method uses a penetrator or indenter to make an impression in a piece of material and then uses the depth of the indentation to calculate a hardness value?
The hardness testing method that uses a penetrator or indenter to make an impression in a material and calculates hardness based on the depth of the indentation is called the Vickers hardness test. In this method, a diamond pyramid indenter presses into the material, and the size of the resulting indentation is measured to determine the Vickers hardness number (HV). This test is applicable to a wide range of materials and provides a continuous scale for hardness values.
What is relative hardness of a mineral can be best tested by?
The relative hardness of a mineral can be best tested by conducting a scratch test against common minerals with known hardness values, such as the Mohs Scale of Hardness. By observing which mineral scratches another, you can determine the relative hardness of the unknown mineral.
What can scratch gypsum but can be scratched by all other minerals?
Talc can scratch gypsum, but can be scratched by all other minerals. Talc is the softest mineral on the Mohs scale, with a hardness of 1, making it easily scratched by minerals with higher hardness values. Gypsum has a Mohs hardness of 2, so talc can leave a mark on it.
How could you determine the hardness rating for a mineral not listed on the scale?
Moh's Scale of Hardness # Talk # Gypsum # Calcite # Fluorite # Apatite # Orthocalse Feldspar # Quartz # Topaz # Corundum # Diamond Has only 10 minerals in it. There are literally 100s if minerals to be found in the rocks that are not used in the scale but that can have their hardness related to the scale. e.g. graphite, galena, beryl, zircon etc.
What two minerals are harder than calcite but softer than quartz?
Fluorite and apatite are two minerals that are harder than calcite but softer than quartz on the Mohs scale of mineral hardness. They have hardness values of 4 (fluorite) and 5 (apatite) respectively, compared to 3 for calcite and 7 for quartz.
Why is the hardness of a mineral important?
The hardness of a mineral is important because it helps in mineral identification. Minerals with different hardness values can be distinguished using the Mohs hardness scale. Hardness can also indicate the durability and wear resistance of a mineral in various applications.
What can you conclude from the hardness brinell values?
Hardness Brinell values provide information on the hardness of a material based on the indentation it makes when a predetermined force is applied. Higher Brinell values indicate a harder material, while lower values indicate a softer material. It is a useful metric for comparing the relative hardness of different materials.
Why was Freidrich Mohs work important?
Mohs created the Mineral Hardness scale in 1822. It is a comparison table showing 10 common minerals and their relative hardness values. Scientists can use it to compare to other unknown minerals and for classification of minerals. In science you always want to be able to compare something to something else. So instead of saying something is soft or hard, the Mohs Scale gives a relative value to the description.
Which properties of minerals can be expressed in numbers?
The crystallographic axes of minerals are expressed as numbers. As such these numbers can also be used to describe the orientation of mineral cleavage planes. The Mohs hardness, specific gravity, and melting point of minerals are also properties that can be expressed numerically.
What is a specific test geologist use to identify minerals?
Geologists commonly use the Mohs hardness test to identify minerals. This test involves scratching the mineral against a set of reference minerals with known hardness values, ranging from talc (1) to diamond (10). By determining where the mineral falls on this scale, geologists can gain insight into its identity. Other tests, such as streak, luster, and specific gravity, may also be employed for a more comprehensive analysis.
Where is Conglomerate on the Mohs Scale?
Oh, dude, Conglomerate isn't actually a mineral, it's a rock made up of different minerals all squished together like a messy sandwich. So, it doesn't have a specific place on the Mohs Scale, which is all about ranking the hardness of minerals. It's like trying to compare apples to, well, a rock sandwich.
