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 […]
What is the value of compressibility factor Z of a gas when I pressure is low II pressure is high?
How can man in middle attack be performed in Diffie Hellman algorithm?
How can man in middle attack be performed in Diffie Hellman algorithm? “The Diffie-Hellman key exchange is vulnerable to a man-in-the-middle attack. After this exchange, Carol simply decrypts any messages sent out by Alice or Bob, and then reads and possibly modifies them before re-encrypting with the appropriate key and transmitting them to the other […]
What are the properties of air Grade 6?
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 […]
What type of reaction is CO2?
What type of reaction is CO2? Combustion reactions involve the reaction of a substance with oxygen gas (O2). It is often referred to as burning. The products of the reaction are oxides of the elements in the reactants. Hydrocarbon combustion leads to the formation of carbon dioxide gas and water vapor. Is C O2 CO2 […]
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 […]
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 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 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 […]
