If a client of yours is having difficulty visualizing a design, what type of drawing would be the easiest to understand? Which of the following is not a pictorial drawing?
Which rays are produced by cobalt in industrial radiography? Horse power of I. Quantities like pressure, temperature, density, viscosity, etc. It satisfies equation of state and its specific heats are constant.
Solid Solution. There is no such wastage in four stroke petrol engine. Why axial flow compressor is preferred for gas turbines for aeroplanes? What are two essential conditions of perfect gas? Manner of loading Static versus dynamic. Some elements exist in more than one crystalline form. List two effects of manganese in plain carbon steels. When added in amounts up to 2.
Also, we have included a few most important frequently asked aptitude questions as well. This branch of engineering has its effect so large and widely prevalent, that there are a number of different areas that make up this branch such as Engineering Mechanics, Heat Transfer, Refrigeration and Air conditioning, Mechanics of Solids, Design of Machinery, Metallurgy, Engineering Design, and Fluid Mechanics to name a few.
What is difference between conjugate beam and continuous beam? Under what circumstances would there be an increase in pressure in a divergent nozzle? Materials lacking this property are anisotropic. It is a solid formed by combination of metallic and non-metallic elements. Boiler tubes, usually are made from carbon steel and are subject to a high rates of heat transfer, b bending stresses due to uneven heating, especially at expanded or welded joints into headers or drums, c external erosion from burners and flue gas, d possible corrosion on the boiler side, and e occasional manufacturing defects.
This collection of questions are surely going to help in various aspects and the details will also increase the confidence of the candidates who are going to appear.
It is a special class of anisotropic materials which can be described by giving their properties in three perpendicular directions e. What do you understand by critical points in iron, iron-carbide diagram? Whether entropy is intensive property or extensive property?
Why fatigue strength decreases as size of a part increases beyond around 10 mm? For pure substances, the heat effects accompanying changes in state at constant pressure no temperature change being evident are known as latent heats. Write any one situation where it is advantageous, state and explain in detail polygon law of forces, please send me all mechanical interview questions in pdf form so I can download and print it…send to my mail ID : pravinpotdar98 gmail.
It improves rolling properties, hardenability, and resistance to wear. Which heating value is indicated by a calorimeter and why? Why high latent heat of vaporisation is desirable in a refrigerant?
Seven factors influencing type of failure are : A plant which initiates, sustains, controls and maintains nuclear fission chain reaction and provides shielding against radioactive radiation is nuclear reactor. Brass is an alloy of copper with zinc; and bronze is alloy of copper with tin. Recently we had provided Civil Engineering Interview Questions.
What harm hydrogen has on property of steel? Eutectoid alloys are the alloys for which two solid phases which are completely soluble become completely insoluble on cooling before a certain temperature called eutectoid temperature.
Fuel cycle a series of sequential steps involved in supplying fuel to a nuclear power reactor. When effect of variations in specific heats is considered then how do maximum temperature and pressure vary compared to air standard cycle? For such instances, we have listed topic wise Mechanical Engineering Questions which can be downloaded from the complete list provided below.
The fundamental idea as to how a seemingly simple volume of strange looking fluid is helping a relatively enormous vehicle move or how a basic concept of friction in a rope and pulley arrangement is being used to operate a lift is what motivates a mechanical engineer. Similarly a material may evidence ductile failure under tensile loading at ordinary testing speed but if load is applied at a high velocity then failure may be brittle.
How heat treatment alters properties of steel? Supercritical boilers do not head heavy drum for separation of steam from mixture of water and steam. What is the relationship between COP of heating and cooling? For aqueous solutions of salts, the specific heat can be estimated by assuming the specific heat of the solution equal to that of the water alone.
Curie point is the temperature at which ferromagnetic materials can no longer be magnetised by outside forces. Why rate of condensation is higher on a polished surface compared to rusty surface? Which is that? Metallic bond is strongest and molecular bond also known as Vander Waals bond is weakest. By excessive treatment the high compressive stresses are introduced but these are balanced by high internal tensile stresses of equal value and the subsurface fatigue cracks may develop in the regions of high tensile stress and lead to early fatigue failure.
How is thermal n affected by weak and rich mixture strength? What type of boiler does not need a steam drum? A state in which a liquid alloy or metal coexists with its crystals is a two-phase system. If austenite containing about 0. How the thickness of thermal boundary layer and thickness of hydrodynamic boundary layer related? It decreases thermal efficiency but increases net output.
Thermal n is high for weak mixture and it decreases as mixture strength becomes rich. These desirable effects partially compensate for the tendency of silicon to lower the creep properties of steel. Which factors influence the type of fracture in failure of a material?
Because it has low frontal area. What is the different between brass and bronze? What is polytropic process? Explain the difference between ferrite, austenite and graphite? Large forgings in alloy steel are particularly sensitive to this phenomenon.
This microstructure is called pearlite. Aluminium is also added to brass to improve corrosion resistance. Further it is very convenient to insert and take out the cover plate from elliptical opening.

Are you civil engineer? Are you capable enough in designing and drawing technically? Are you interested in the construction field? Then follow us on wisdom jobs online site and discover your dream job? Engineering drawing is a type of technical drawing used to fully and clearly define requirements for engineered items.
AutoCAD, developed by Autodesk, is a computer design software used by architects, engineers, and mechanical students. The first release of the software happened in AutoCAD helps to design complex infrastructure or product concepts before going it to production and provides the team with information about the feasibility and precision of the design. It helps in saving valuable time and resources. Any operating system that supports graphics controllers can run AutoCAD. Also, it is free software that can be downloaded directly through online.

Engineering projects require a lot of logical and analytical thinking to solve problems that occur on the job. This question gives you an understanding of how applicants think through and solve issues. What to look for in an answer:. I had to expand the data that I typically worked with to include climate change information, as the different weather patterns increased the risk factors. Engineers have to collaborate with many departments, teams and individuals during projects. Applicants should be skilled at verbal and written communication of complex engineering concepts, even when they're not talking to fellow engineers. For example, if I'm in a meeting with a lot of sports fans, I might relate what I'm saying to the way a stadium is structured.

Беккер старался не обращать внимания на легкий запах перца. Меган сказала, что, если тереть глаза, будет только хуже. Он даже представить себе не может, насколько хуже.
- Потом мы запустим его снова, а Филу скажем, что ему все это приснилось. Стратмор задумался над ее словами, затем покачал головой: - Пока не стоит. ТРАНСТЕКСТ работает пятнадцать часов. Пусть пройдут все двадцать четыре часа - просто чтобы убедиться окончательно.
Всем известно, что невзламываемый алгоритм - математическая бессмыслица.
