b) Thermal barrier coating. Cement, aluminum, engineering ceramic, super alloy, steel and glass
Answer:
Answer explained below
Explanation:
3.] a] A turbine blade is the individual component which makes up the turbine section of a gas turbine. The blades are responsible for extracting energy from the high temperature, high pressure gas produced by the combustor.
The turbine blades are often the limiting component of gas turbines. To survive in this difficult environment, turbine blades often use exotic materials like superalloys and many different methods of cooling, such as internal air channels, boundary layer cooling, and thermal barrier coatings. The blade fatigue failure is one of the major source of outages in any steam turbines and gas turbines which is due to high dynamic stresses caused by blade vibration and resonance within the operating range of machinery.
To protect blades from these high dynamic stresses, friction dampers are used.
b] Thermal barrier coatings (TBC) are highly advanced materials systems usually applied to metallic surfaces, such as on gas turbine or aero-engine parts, operating at elevated temperatures, as a form ofexhaust heat management.
These 100μm to 2mm coatings serve to insulate components from large and prolonged heat loads by utilizing thermally insulating materials which can sustain an appreciable temperature difference between the load-bearing alloys and the coating surface.
In doing so, these coatings can allow for higher operating temperatures while limiting the thermal exposure of structural components, extending part life by reducing oxidation and thermal fatigue.
In conjunction with active film cooling, TBCs permit working fluid temperatures higher than the melting point of the metal airfoil in some turbine applications.
Due to increasing demand for higher engine operation (efficiency increases at higher temperatures), better durability/lifetime, and thinner coatings to reduce parasitic weight for rotating/moving components, there is great motivation to develop new and advanced TBCs.
Answer:
a)-Bin stock items free issue
Explanation:
Bin stock items free issue items are similar to the free issue items, but their access is limited.
Bin stock items free issue items are similar to the free issue items, but their access is limited.
Web application 3’s “Where’s the Beef” exploit can be seen in the screenshot provided. In order to mitigate this vulnerability, developers should take measures to ensure that input validation is performed on all data.
Additionally, developers should enforce strict rules on which characters are allowed in user inputs and reject all requests that don’t follow these rules. Finally, developers should implement best practices such as password hashing to ensure that user data is secure.
Developers should use secure coding techniques, such as sanitizing user input and properly escaping HTML output, to protect against injection-based attacks. Also, developers should implement authentication and authorization techniques to ensure that only authorized users have access to sensitive data. Furthermore, developers should use an up-to-date web application firewall to protect against known exploits, and use secure protocols such as HTTPS to protect data in transit. Finally, developers should ensure that software is kept up-to-date and patched to prevent exploitation of known vulnerabilities.

Answer:
(b) False
Explanation:
Isothermal process is a process in which temperature is constant ,heat can be transferred but temperature is constant and as the temperature is constant so internal energy is also constant
In other hand in adiabatic process there no transfer of heat and internal energy also changes
So the given statement is false statement
Answer:
True
Explanation:
For steels, we can assume the endurance limit measured by rotating beam tests is the 50% of the ultimate tensile strength (UTS) as long as the UTS is equal to or less than 200 kpsi (1400 MPa).
Also, It is a simplistic rule of thumb that, for steels having a UTS less than 160 kpsi, the endurance limit for the material will be approximately 45 to 50% of the UTS.
