How far behind someone should you drive? two seconds What is required before securing the car? You begin by stopping the vehicle, set your parking brake, then place the gear selector in park, turn off accessories, turn off ignition and remove key, remove any occupant restraint such as seat belt and valuables from sight, check […]
How does heat treatment affect yield strength?
How does heat treatment affect yield strength? The heat treatment develops hardness, softness, and improves the mechanical properties such as tensile strength, yield strength, ductility, corrosion resistance and creep rupture. These processes also help to improve machining effect, and make them versatile. Does Young’s modulus change with heat treatment? Since the Young modulus is related […]
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 […]
How do you increase the toughness of steel?
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 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 […]
How do I change text to mtext?
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 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 […]
