Spider silk. The reason it seems so weak when you accidentally walk through a web is because it is so thin. If you could make spider silk thicker it would be stronger than a steel cable.
Steel. It's a much stronger and much less expensive material.
it is made out of steel
It was made of steel.
steel and plastic
Metal or steel
Yes, they are steel.
Robots are usually not made of steel, they are usually made of a lighter material like an aluminum alloy
threads are made by high carbon steel and high speed steel. the body of die made by steel and carbon steel
The material the mounting plate is made of is plated steel. To provide stability in the product.
By stronger, we need to define the loading conditions of the rod or pipe. The strength of a rod or pipe is typically evaluated with axial, transverse (bending), and torsion loads. With the same diameter and the same material, a solid rod is stronger than a hollow pipe. However, with the same weight and material, the hollow pipe is stronger than a solid rod. Because a hollow pipe is lighter than a solid rod at the same diameter, the hollow pipe would have a larger diameter in order to match weights with the solid rod and a larger diameter rod or pipe is stronger than a smaller diameter one.
High carbon steel is stronger than low carbon steel with proper heat treatment. Thus, it will fail at a much higher load. ------------------------------------------------------------- Note: not all shear pins are high carbon heat treated steel. The pin needs to be nearly as strong, but not stronger than the material in which it is used, so that it shears off before the material it protects is damaged. thus a shear pin for a bronze shaft may actually be made of copper. Obviously the stronger the material, or larger the diameter of the pin, the more load it can handle, but it needs to shear off before the material it protects is crushed. I'd assume that a high carbon steel shear pin is being used on a machine made of some high tensile strength stainless alloy.
