Rockwell C scale
SOFT
The Rockwell scale measures the hardness of materials, particularly metals, using a standardized method that involves applying a specific load to an indenter and measuring the depth of penetration. Different Rockwell scales (e.g., A, B, C) are used for various materials, with the C scale commonly applied to harder materials like steel. The scale provides a straightforward numerical value that indicates hardness, where higher numbers correspond to harder materials. Thus, the hardness of a file, which is typically made from high-carbon steel, would be relatively high on the Rockwell scale, often around 60 HRC or more.
your bones can break but to the steel framework of a skyscraper is way to hard
Hard, cold, shiny, rusty, to name a few.
I is an exhaustible resource because it is steel not water, gas or sun. So it is really hard to find.
its hard to say with certainty, but probably an accumulator register.
A typical steel knife would be in the 5-5.5 range on the Mohs scale.
The hardness of the mineral pyrite, or Fool's Gold, is about 6 on the Mohs hardness scale. That's a little harder than a steel knife blade, but not as hard as the mineral quartz
Halite is hard. It can be scratched by a steel file and a knife with difficulty
The answer depends on the scale used. which depends on the teacher and how hard the quiz was. It is probably a C . Maybe a B.
hard
use steel.
Cold hard steel
The hardness of steel is incomprehensible. It is very hard.
Mild steel
Made of steel; consisting of steel., Resembling steel; hard; firm; having the color of steel.
A scriber is made from very hard steel.A scriber is made from very hard steel.
