A good and long-term relationship between organization and its suppliers helps to manage a more efficient process in inventory management, material management and delivery system. It will also assure that the supply is stable and available when needed.Important thing about just-in-time inventory practice is that companies should build trust and have good relationship with their suppliers because just-in-time practice requires stable, fast and flexible supply of materials. Only if they have good relationship can this be done.
An adhesive which is capable of filling up to 1/16 void between two mating surfaces is known as gap filling adhesive. It should possess high durability and strength.
Industrial Relation refers the any relationship between employees or trade unions , managers or employer organizations and the state. Ayesha Koralage University Of Sri Jayewardenepura
Transformational leadership includes a committed relationship between the leader and their followers. The elements of this leadership are idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration.
Bond strength is related to mineral hardness. Minerals with strong chemical bonds tend to have high hardness, while minerals with weaker bonds have lower hardness. This is because the strength of the bonds affects how easily the mineral can be scratched or deformed.
In Vickers hardness test the for used is much lighter than the force used in Rockwell hardness test, The Rockwell hardness test is the considered to be the most routinely used technique to measure the hardness of materials because of its simplicity and because it does not require specific skills in order to perform it.
The difference between strength and hardness is that the strength refers to the force that is present between the bonds. Strength attributes to how strong or weak the force between the bonds. Hardness refers to the nature of the force, which basically is how rigid or flexible the bonds between particles.
when ductility increase hardness decrease
Well, honey, converting Barcol hardness to Vickers hardness ain't exactly a walk in the park. You'll need to consult some fancy conversion charts or formulas to make that happen. It's not as simple as snapping your fingers, but with a little bit of elbow grease, you'll get there.
the relationship between grain size and strength can be determined by the Hall- Patch relationship of Strength of materials.
Hardness is the property of a material that resists indentation. Harder materials have stronger bonds between their atoms, making them more difficult to deform or dent. Hardness is typically measured using methods such as the Mohs scale or the Vickers hardness test.
There is no basis for comparison between the two. An iceberg's "strength" is its mass and hardness. A tornado's strength is its wind speed.

Grade 10.9 bolts or capscrews have a minimum tensile strength of 1040N/mm2 and a hardness of 320 - 380Hv10. Grade 12.9 bolts or capscrews have a minimum tensile strength of 1220N/mm2 and a hardness of 385 - 435Hv10. The 12.9 fastener is therefore a higher grade (hardness and tensile strength) fastener compared with 10.9 grade
what is the difference between Shore-A Hardness & Barcol Hardness
the hardness of iron decreases with increase in brittleness in general..however when the temp is increased, the elasticity increases and the brittleness reduces, it continues to show the increasing trend in hardness until a transition temperature, after which the hardness starts decreasing again.
