How do you measure diameter?
Internal diameter.
How does he find the measure of a radius if he knows the measure of the diameter?
The radius of a circle is half the diameter.
How did they measure the diameter or radius of earth?
with a big tape measure
How do you figure out the circumference of something without knowing the diameter?
If you know the radius, double that to get diameter. If you have neither radius or diameter, then measure around the outside.
How do you measure the diameter of a circle?

What is a Brinell hardness tester used for?
The Brinell hardness tester was invented to measure the hardness of materials using an indentation. Applied force is measured against the force, diameter of indentation and indenter.
How do you calculate Brinell hardness number?
Brinell hardness number is calculated by dividing the applied load in kilograms by the surface area of the resulting indentation in square millimeters. The formula is expressed as: ( \text{Brinell Hardness Number (BHN)} = \frac{\text{Applied Load (kg)}}{\pi \times \text{Indentation Diameter (mm)} \times (\text{Diameter of Ball (mm) - Indentation Diameter (mm)})} ).
What is the Brinell hardness test used for?
The Brinell hardness test is a standardized test in material science. It measures the hardness of a metal by measuring the indentation on the material caused by an indenter.
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.
What is the main difference between rockwell and brinell hardness?
Both are two different scales of hardness measurement.
What is the unit of hardness?
The unit of hardness is typically expressed in terms of Rockwell (HRC), Vickers (HV), or Brinell (HB) scale depending on the specific test method used. Hardness is a measure of a material's resistance to deformation or indentation.
What are the advantages and disadvantages of brinell hardness test?
the formula of B.H.N is give less accurate value when the indentation is more. It has only one scale And applied only to some materials.
What is the difference between brinell and rockwell hardness tester?
Brinell hardness tester uses a ball to apply a specified load on the material surface, measured by the resulting indentation size. Rockwell hardness tester uses a diamond cone or steel ball to penetrate the material, and hardness is calculated based on the depth of penetration. Brinell is better for softer materials and larger test areas, while Rockwell is more versatile and provides different scales for various materials.
What is a durometer used to measure?
A durometer is an instrument that is used to measure hardness. Specifically, a durometer can be used to measure a material's resistance to indentation.
Formula for Vickers to Brinell conversion?
The formula to convert Vickers to Brinell hardness is: Brinell Hardness = (2.025 x Vickers Hardness).
What is the radius of a circle 26.4 cm?
13.2 cm, if the given measure is the diameter.13.2 cm, if the given measure is the diameter.13.2 cm, if the given measure is the diameter.13.2 cm, if the given measure is the diameter.
When did Johan August Brinell die?
Johan August Brinell died in 1925.
