What is used for quenching? Water is one of the most efficient quenching media where maximum hardness is desired, but there is a small chance that it may cause distortion and tiny cracking. When hardness can be sacrificed, mineral oils are often used. What is the difference between annealing and quenching? During the annealing process, […]

What is high strength steel used for in cars?
What is high strength steel used for in cars? New grades of Advanced High-Strength Steels enable carmakers to reduce vehicle component weight by 25-39% and total vehicle weight by 8-10% compared to conventional steel. What are advanced high strength steels? Advanced High-Strength Steels (AHSS) are complex, sophisticated materials, with carefully selected chemical compositions and multiphase […]
How do you say thank you for help?
What does a tensile test tell you?
What does a tensile test tell you? A tensile test applies tensile (pulling) force to a material and measures the specimen’s response to the stress. By doing this, tensile tests determine how strong a material is and how much it can elongate. How do you measure the tensile strength of a material? In a simple […]
What is a technology engineer called?
What is a technology engineer called? Graduates with an Engineering Technology degree are often called “technologists,” while students who complete two-year engineering technology programs are called “technicians.” These individuals begin their careers in entry-level positions that may involve the design and application of engineering concepts or … What is a technologist vs engineer? Technologists are […]
How do you calculate wet bulb temperature from dry bulb temperature?
How do you calculate wet bulb temperature from dry bulb temperature? By definition, wet-bulb temperature is the lowest temperature a portion of air can acquire by evaporative cooling only. When air is at its maximum (100 %) humidity, the wet-bulb temperature is equal to the normal air temperature (dry-bulb temperature). What is dry bulb temperature […]
What happens to pressure when area increases?
What happens to pressure when area increases? Answer. As pressure and area are indirectly proportional to each other . so , if area increases , pressure decreases. How can pressure be increased? The pressure exerted by the gas can be increased by: increasing the number of collisions of gas molecules per unit time by increasing […]
What process is the removal of materials?
What process is the removal of materials? Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. Machining can also be performed on an existing part, such as a casting or forging. In which process various […]
