What is natural laminar flow? [¦nach·rəl ′lam·ə·nər ′flō] (aerospace engineering) Airflow over a portion of the wing such that local pressure decreases in the direction of flow and flow in the boundary layer is laminar rather than turbulent; frictional drag on the aircraft is greatly reduced. What are 2 characteristics of all fluids? Lesson Summary […]
How do you know if price elasticity of demand is elastic or inelastic?
How do you know if price elasticity of demand is elastic or inelastic? A product is considered to be elastic if the quantity demand of the product changes drastically when its price increases or decreases. Conversely, a product is considered to be inelastic if the quantity demand of the product changes very little when its […]
How does a hearing aid microphone work?
How does a hearing aid microphone work? Hearing aids work by amplifying sound through a three-part system: The microphone receives sound and converts it into a digital signal. The amplifier increases the strength of the digital signal. The speaker produces the amplified sound into the ear. How does a microphone converts sound waves into an […]
What are common work contexts for architects?
What are common work contexts for architects? Work Environment Architects spend much of their time in offices, where they develop plans, meet with clients, and consult with engineers and other architects. They also visit construction sites to prepare initial drawings and review the progress of projects to ensure that clients’ objectives are met. What are […]
How do you pass a string as an argument to a function in C?
What is elastic strain recovery?
What is elastic strain recovery? Elastic recovery, or resilience, is a measure of the ability of an elastomer to return to its original shape when a compression load is removed. Ideally a seal should have a good resilience which can be largely controlled by compounding. What happen when bodies are deformed beyond elastic limit? When […]
How do you find mass when given force and acceleration?
What is an acceptable decibel level?
What is an acceptable decibel level? Decibel Level Sounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time. Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher […]
What is the density expressed in SI units?
What is the density expressed in SI units? For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre. Density can also be expressed as kilograms per cubic metre (in metre-kilogram-second or SI units). For example, the density of air is 1.2 kilograms per cubic […]
