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
High Hard P20 steel typically has a Rockwell Hardness in the range of 28 to 32 HRC (Rockwell C scale) after heat treatment. This hardness level provides a good balance of toughness and wear resistance, making it suitable for various applications, including mold making. The specific hardness can vary depending on the exact composition and heat treatment process used.
Hard, cold, shiny, rusty, to name a few.
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.

use steel.
Cold hard steel
The hardness of steel is incomprehensible. It is very hard.
Mild steel
A scriber is made from very hard steel.A scriber is made from very hard steel.
