Why structure properties use relationship is considered very important in engineering materials? A material in a product possesses a set of properties—strength, hardness, conductivity, density, colour and so on—chosen to meet the design requirements. The structure property relationship (Table 1.2) gives the material engineer a basis for understanding the nature and behaviour of a wide […]

What is the diametral pitch of a gear? Diametral Pitch is the Number of Teeth to each Inch of the Pitch Diameter. How do you calculate the number of teeth on a gear? First, you need to define a series of concepts to perform the spur gear calculations: The number of teeth (z). This value […]

What are volatile solids in wastewater? Volatile solids are a substance that can easily transform from its solid phase to its vapor phase without going through a liquid phase. The amount of volatile solids in wastewater is frequently used to describe the strength of the waste. The more volatile solids present in wastewater, the stronger […]

What is a polymeric material? Image credit: Maksim) Polymers are materials made of long, repeating chains of molecules. The materials have unique properties, depending on the type of molecules being bonded and how they are bonded. Some polymers bend and stretch, like rubber and polyester. Others are hard and tough, like epoxies and glass. What […]

In which filter the output and input voltage are equal in amplitude for all frequencies? all-pass filter What is the function of filter circuit? A filter is a circuit capable of passing (or amplifying) certain frequencies while attenuating other frequencies. Thus, a filter can extract important frequencies from signals that also contain undesirable or irrelevant […]

What is the meaning of significant digit? : any of the digits of a number beginning with the digit farthest to the left that is not zero and ending with the last digit farthest to the right that is either not zero or that is a zero but is considered to be exact. — called […]

Are satellites outside the atmosphere? Satellites are sent into space by a rocket launched from the ground with enough energy (at least 25,039 mph!) to get outside our atmosphere. Satellites do carry their own fuel supply, but unlike how a car uses gas, it is not needed to maintain speed for orbit. Which layer of […]
