Is truss a two force member? Trusses are structures that are composed entirely of two-force members. Each member of a truss is assumed to be a straight member that can only have forces applied on the ends of that member. Which members of the frame are two force members? Why the Forces Must Be Equal, […]
What is the ductile to brittle transition temperature of steel?
What is the ductile to brittle transition temperature of steel? around 0°C What is the ductile to brittle transition and why is it important? 1 Brittle-to-ductile transition. The brittle-to-ductile transition is essential for the understanding of fracture processes. Experiments indicate that solids are brittle at very low temperature, and their toughness become much higher at […]
What is the difference between accuracy and precision with example?
What is the difference between accuracy and precision with example? Accuracy is how close a value is to its true value. Precision is how repeatable a measurement is.

What happen with the lubricant molecules as you increase the temperature?
What happen with the lubricant molecules as you increase the temperature? The Effects of High Temperature on Lubricants When lubricants reach high temperatures, oxidation and additive depletion occurs. When a lubricant’s temperature rises, molecules in the fluid become hyperactive as gas is released and lighter parts of the fluid vaporize. This can permanently damage operating […]
