the relation between the diameter of indentation (d) and the hardness? is when indentation diameter increases the BHN decreases . . .

Ahmed Adnan Ahmed 11-14 said...

as the diameter increase ,the hardness will decreases.

Rashid Abdulla - 11;14 said...

When the Diameter increase the hardness decrease

mohammed hassan _ 11-14 said...

when diameter indention increase hardness will decrees and became more hard not easily.

Mansoor Mohammed 11-13 said...

As the diameter increases, the hardness decreases.

Mohammed Jamal - 11.13 said...

as the diameter increase the hardness will decreases :P

majid obaid 11.13 said...

when the indentation increase the hardness will decrease and when the indentation decrease the hardness will increase.

saif alshamsi 11-13 said...

when diameter increase , the hardness decreases,and it will harder.

saif saqer said...

When the diameter of indentation is bigger the material has less hardness

When the diameter of indentation is
smaller the material has more hardness

majid aubdullah 11-13 said...

diameter increase and i think the hardness will decreases.

Mohammed Habib 11-13 said...

If the indentation is big then the hardness of the material is less, and if the indentation is small then the hardness of the material is more.

sultan mohammed h 11-13 said...

when the diameter increase the hardness decrese

salim mohammed 11-13 said...

when the diameter increase the hardness will decrease, and when the diameter decrease the hardness will increase

abdulla mohammed said...

as the diameter increase ,the hardness will decreases.

mohammed saeed hashel said...

-The relation between the diameter of indentation
-The diameter will increase and the hardnes will high

aref abdullah 11-13 said...

The relation between the diameter of indentation ?
the diameter will increase and the hardness will decreases

ahmed ali 11-13 said...

if a diameter increase the hardness will decrees and it will be more hard and not easy.

Mohamed Ahmed Mohamed Ali 11-15 said...

when the diameter increase the hardness decrease

Mansoor 11-15 said...

Diameter is going to increase ,And the hardness is going to decreases.

essa ahmed 11:15 said...

if the indentation diameter decrease the hardness it will increase.
and if indentation increase diameter it will decrease.

Omran Hassan 11-15 said...

If the diameter increase the hardness will decrease

If the diameter decrease the hardness will increase

Omran Abdulla saif 11-15 said...

as long as the diameter increases
The hardness keep decrease.

Ali Jassim-11.15 said...

When the diameter of the indentation
increase the hardness will decrease and it will become harder than before

ali abdulla mohammed 11-15 said...

If the diameter increase the hardness will decrease

abdulla mubarak 11-15 said...

if the diameter increase the hardness decreases , and if the diameter decreases the hardness increase

yousef saif 11-15 said...

when ever you want to make the indentation test you should use the steel ball
that's what took it as great idea

yousef saif 11-15 said...

that's what took it as great idea

mana abdelrahman 11-15 said...

its have different between the diameter for ball and the metal
the diameter for the ball every time is 12 or 10 but for the metal we have to measure the diameter.

mohammed ahmed mohammed ahmed hussain 11-14 said...

* When the indentation of the diameter increases the hardness decreases *

Majid Adnan 11-15 said...

when the hardness decrease the diameter increases and the opposite.

Abdulla Mohammed 11-15 said...

the diameter increase, the hardness will decreases.

Hamad Adnan 11-15 said...

if the diameter increase the hardness will decrease

Omar Ibrahim 11-15 said...

The indentation diameter small it means have more hardness.

Nasser_11-15 said...

When we see that the indentation diameter is small, that means it is more hardness.
so when the diameter increase the hardness decrease

abdullaziz omar and khalid jamal 11-12 said...

the indention diameter is increase and the brinell hardness number is decrease.

essa darwish 11-12 said...

when the diameter of indetion increase the hardness will decrease

ibrahim abdulla said...

the indention increase the inductor decrees

khalid ali 11-14 said...

the diameter increase ,and hardness will decreases
