Why does steel become brittle at low temperatures? Cooling just about anything to liquid nitrogen temperatures makes it more brittle than at higher temperatures. At higher temperatures, defects in the crystal lattice of a material are more mobile. At lower temperatures, the nearby atoms in the crystal lattice do not move and long cracks can […]

When a fluid flows over an object the pressure or form drag?
When a fluid flows over an object the pressure or form drag? A body moving through a fluid experiences a drag force, which is usually divided into two components: frictional drag, and pressure drag. Frictional drag comes from friction between the fluid and the surfaces over which it is flowing. What does the pressure at […]
How do I choose a chain size?
How do I choose a chain size? Chain Wear Factors Two important factors, resistance to wear and resistance to fatigue, should be considered when determining chain size and quality. Generally, these two factors dictate roller chain life and failure. How do you design a chain drive? Type of Chain. Roller Chain is selected for the […]
