What is the volume of a 10 mL graduated cylinder? If you look at a 10mL graduated cylinder, for example, the smallest graduation is tenth of a milliliter (0.1mL). That means when you read the volume, you can estimate to the hundredths place (0.01mL). Use the bottom of the meniscus to determine the volume in […]
Why must powder metals be sintered in controlled atmosphere?
Why must powder metals be sintered in controlled atmosphere? A basic function of a sintering atmosphere is to protect metal parts from the effects of contact with air. Atmospheres must be maintained at sufficient pressure and flow rate to prevent infiltration of air through furnace openings. How does a sintering furnace work? The sintering process […]

Which symbol is used to obtain the address of a variable from the memory?
Which symbol is used to obtain the address of a variable from the memory? variable ampersand Which function provide the address of the variable in memory? We can see the location of the memory address of that value with the id() function. Think of that long number as a storage jar. I can check the […]
What type of aluminum is used for casting?
What type of aluminum is used for casting? A380 Aluminum Alloy The most popular alloy for aluminum die casting is A380. We use A380 because it has demonstrably the best combination of physical and mechanical properties for casting, including being lightweight, very strong at high temperatures and corrosion resistant. How many types of die casting […]
What was one major impact of the assembly line on the worker?
What was one major impact of the assembly line on the worker? The assembly line sped up the manufacturing process dramatically. It allowed factories to churn out products at a remarkable rate, and also managed to reduce labor hours necessary to complete a product—benefiting many workers who used to spend 10 to 12 hours a […]
What conditions favor formation of substitutional alloys?
What conditions favor formation of substitutional alloys? What conditions favor formation of substitutional alloys? Substitutional alloys are formed when the two metallic components have similar atomic radii and chemical bonding characteristics. For example silver and gold. What is substitutional alloy? Substitutional alloys are formed when the metallic components have similar atomic radii and chemical-bonding characteristics. […]
What is the relation between elastic constants?
What is the relation between elastic constants? Young’s modulus, bulk modulus and Rigidity modulus of an elastic solid are together called Elastic constants….Elastic constant formula. Formula SI Units The relation between Young’s modulus and bulk modulus E=3K\left ( 1-2\mu \right ) N/m2 or pascal(Pa) What is the interrelationship between the three constants? All three elastic […]
What does Clausius inequality mean?
What does Clausius inequality mean? The Clausius Inequality applies to any real engine cycle and implies a negative change in entropy on the cycle. That is, the entropy given to the environment during the cycle is larger than the entropy transferred to the engine by heat from the hot reservoir. What is Clausius statement of […]
