What are the properties of air Grade 6? Let’s review everything we learned about air, or the mixture of gases, water vapor, and other materials. Air takes up space. Air is made of gases, including nitrogen, oxygen, water vapor, and other materials. Air exerts pressure. Air has weight. Air can be compressed. Air is affected […]
How do you calculate the coefficient of a FIR filter?
How do you calculate the coefficient of a FIR filter? h(N-1)[cos((N-1)w) – jsin((N-1)w)] , or Consider a DC (zero Hz) input signal consisting of samples which each have value 1.0. After the FIR’s delay line had filled with the 1.0 samples, the output would be the sum of the coefficients. Therefore, the gain of a […]
How strong is galvanized steel pipe?
How strong is galvanized steel pipe? The mechanical properties of this type of pipe varies according to the method of manufacturing. However, the typical yield strength is around 30,000 psi. What is galvanized steel pipe used for? Galvanized steel pipe is covered with a zinc material to make the steel pipe more resistant to corrosion. […]
What are the roles of structural engineer?
What are the roles of structural engineer? Structural Engineer Responsibilities: Prepare reports, designs, and drawings. Make calculations about pressures, loads, and stresses. Consider the strength of construction materials and select appropriately. Provide technical advice on safe designs and construction. Obtain planning and/or building regulations approval. What are the three primary duties of an engineer? Engineer […]
What gives the aircraft directional stability?
What gives the aircraft directional stability? Yawing or directional stability is the most easily achieved stability in aircraft design. The area of the vertical fin and the sides of the fuselage aft of the CG are the prime contributors that make the aircraft act like the well known weather vane or arrow, pointing its nose […]
Why do ceramics have a high melting point?
Why do ceramics have a high melting point? Ceramic Materials have high heat capacity and have both ionic and covalent bonds. The ability of a material to absorb heat from its surrounding isits heat capacity. Since ionic bonds are strong and unidirectional the melting point of ceramics is higher. What are the properties of ceramics? […]
What are the mechanisms of heat transfer?
What are the mechanisms of heat transfer? The Three Mechanisms of Heat Transfer: Conduction, Convection, and Radiation. How do the three 3 major processes of heat transfer affect the temperature of the earth? Answer: The heat is transferred by three major processes- Conduction [solid material] – In conduction the heat is transferred through particles to […]
How do you control shrinkage in injection Moulding?
How do you control shrinkage in injection Moulding? By changing temperatures, pressures, and packing and cooling times, it is possible to mitigate shrinkage. By applying pressure to a liquid plastic, the molecules can be compressed into a smaller volume which enables more material to be injected into the mould to compensate for shrinkage. How do […]
What process do engineers use to solve problems?
What process do engineers use to solve problems? Engineers will often use reverse-engineering to solve problems. For example, by taking things apart to determine an issue, finding a solution and then putting the object back together again. Engineers know how things work, and so they constantly analyse things and discover how they work. How can […]
How do you calculate output speed?
How do you calculate output speed? Calculating Output Speed Using Pulley Diameters and Input Speed RPM Output/RPM Input = Multiplication Factor. On a belt-driven fan the two primary speeds required are the RPM of the Motor and the RPM of the fan. Formula. RPM Input/RPM Output = Diameter Out/Diameter In. Formula. RPM Input/RPM Output = […]
