How do you increase the toughness of steel? As-quenched, martensitic steel is strong, but often notably brittle. In order to increase ductility and toughness, martensite is heat-treated by a process called tempering1,2,3. Strength typically decreases with increasing tempering temperature and time, and a corresponding increase in toughness is expected. How do I test my hardness? […]
What are the four tests for flexibility in FMS research?
What are the four tests for flexibility in FMS research? The following are four reasonable tests of flexibility in an automated manufacturing system: Part variety test. Can the system process different part styles in a nonbatch mode?. Schedule change test. Can the system readily accept changes in production schedule, and changes in either […]
What are the different types of die casting?
What are the different types of die casting? To produce light alloy castings, three of the most common technologies are: high pressure die casting, gravity die casting and low pressure die casting. Each technology can support permanent casting process with gravity and low pressure also able to support semi-permanent casting processes. What are the advantages […]

Is relative roughness dimensionless?
Is relative roughness dimensionless? Since the relative roughness is a dimensionless number, both the absolute roughness and diameter must carry the same units. What is equivalent roughness? The equivalent roughness of a mine roadway can be defined. as the roughness of a circular pipe, of which diameter is. equal to the hydraulic diameter of the […]
What is conjugate depth in hydraulic jump?
What is conjugate depth in hydraulic jump? In fluid dynamics, the conjugate depths refer to the depth (y1) upstream and the depth (y2) downstream of the hydraulic jump whose momentum fluxes are equal for a given discharge (volume flux) q. The depth upstream of a hydraulic jump is always supercritical. Why momentum equation is used […]
What process results in an increase of entropy?
What process results in an increase of entropy? Increasing the number of molecules in a system also increases the number of microstates, as now there are more possible arrangements of the molecules. Therefore, any change that results in a higher temperature, more molecules, or a larger volume yields an increase in entropy. What are the […]
What are the 7 steps in identifying analysis at a forensic case?
What are the 7 steps in identifying analysis at a forensic case? Terms in this set (7) secure the scene. separate the witnesses. scan the scene. seeing the scene (taking photographs) sketch the scene. search for evidence. secure the collected evidence. What are the six phases of the forensic investigation process? There are following six […]
What happened to farmers in the 1930s?
What happened to farmers in the 1930s? When prices fell they tried to produce even more to pay their debts, taxes and living expenses. In the early 1930s prices dropped so low that many farmers went bankrupt and lost their farms. Some farmers became angry and wanted the government to step in to keep farm […]
How does a CNC machine work?
How does a CNC machine work? The CNC controller works together with a series of motors and drive components to move and control the machine axes, executing the programmed motions. On the industrial machines there is usually a sophisticated feedback system that constantly monitors and adjusts the cutter’s speed and position. What is CNC machine […]
