Answers detailed info, linux interview questions and answers pdf for freshers tips interview lamaran kerja competency based interview questions for customer.
Sap Oops Interview Questions And Answers Whether individual components in composite materials retain their characteristics or not? Manner of loading, and the rate of loading promote transition from ductile to brittle fracture. It is a solid formed by combination of metallic and non-metallic elements. Give one example of metal classified as per structure as BCC, FCC, HCP and CCP. What is the name of solid solution of carbon in alpha iron and delta iron ? Pearlite is eutectoid mixture of ferrite and cementile. Roughness, enthalpy, toughness, and hardness respectively. Large forgings in alloy steel are particularly sensitive to this phenomenon. The lower temperature form is known as “alpha”-iron and the higher temperature form as “delta”-iron.

Manual Testing Interview Questions Asked In Infosys If percentage elongation of a material is more than 200%, it is classed as ? A stress in excess of elastic limit, with no external force to oppose it, will relieve itself by plastic deformation until it reaches the value of the yield stress. Why fatigue strength decreases as size of a part increases beyond around 10 mm? Creep is low and progressive deformation of a material with time under a constant stress at high temperature applications. Normal carburising/nitriding treatments increase volume due to phase transformation at Surface and introduce residual compressive surface stress and thus increase the fatigue strength. How oxygen can be removed from steel during melting? Oxygen can be removed by adding elements such as manganese, silicon or aluminium which, because of their high affinity for oxygen, react with it to form non-metallic oxides which rise into the slag. Some elements exist in more than one crystalline form. Iron exists in two forms of cubic pattern, namely body centered cubic (bcc) and face-centered cubic (fee). What is the difference between alpha iron, delta iron and gamma iron ? Frequently asked Technical and HR Job Interview Questions and answers on C, struts, data warehousing, PHP, Manual testing, software testing, networking.
TOP MECHANICAL ENGINEERING Interview Questions and It is a special class of anisotropic materials which can be described by giving their properties in three perpendicular directions e.g. In screw dislocation the lattice atoms move fom their regular ideal positions. Fibres are liable to maintain this and thus have high specific strength. For ductile materials, theories of failure used are maximum shear stress theory, and maximum energy of distortion theory; while for brittle materials, theory of maximum principal stress, and maximum strain are used. It depends on boundary layer configuration, fluid properties and temperature difference. Which is the common element between brass and bronze ? Alloys possess typical properties inherent in the metallic state.

Ethernet Interview Questions And Answers An elastomer is a polymer when its percentage elongation rate is ? Perfection of material conditions is possible at lower sizes and as size increases, it is not possible to attain uniform structure of the material. Fatigue is the reduced tendency of material to offer resistance to applied stress under repeated or fluctuating loading condition. While normal carburising and nitriding surface treatments increase fatigue strength, excessive treatment may decrease the fatigue strength. 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. List at least two factors that promote transition from ductile to brittle fracture. Explain the difference between pearlite and cementile ? Give one example each of the following proportion of materials dimensional, physical, technological and mechanical. For which parts the Wahl factor and Lewis form factor used ? Steels which have had most of their dissolved oxygen removed are called “fully killed steels”. Hydrogen cannot be removed easily from molten steel. Execessive hydrogen results in the formation of small fissures often described as hairline cracks or flakes in the steel. The bcc form of iron exists between room temperature and 910°C, and between 1400°C and the melting point at 1539°C. CCNP Job Interview Questions & Answers Q1. The Ethernet and IEEE 802.3 standards define what three physical wiring standards that operate at 10 Mbps?
Business Analyst Interview Questions And Answers PDF If a material exhibits same mechanical properties regardless of loading direction, it is isotropic, e.g., homogeneous cast materials. A combination of phases in a state of equilibrium is called a system. Question Tell me what you understand about an alternate flow in use case? Answer This is the flow that will come into action, when there is a failure in the
