Mechanical Engineers (Mechanical engineer interview questions)

This blog  page for Mechanical Engineers .It can give basic ideas and concept related topics of which can to know for knowledge.This is important to all of basic ideas and new technology related information and growing knowledge which is important to all.

first question on mind what is mechanical engineering?

Mechanical Engineering is applied engineering of physics, and materials science principles to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering.

The fundamental of mechanical engineering and design and manufacturing like also basic fundamental automobile engineering, mechanics,basic knowledge of mechanical engineering   ,concepts of mechanical engineering require develop new thing and mechanical engineer interview questions.

How to generate this concept in mind and how to to applied on machinery and all of that, Such a nice field of mechanical engineering .

1. What is engineering?
   Engineering is the creative application of science, mathematical methods, and empirical evidence to the innovation, design, construction, operation and maintenance of structures, machines, materials, devices, systems, processes, and organizations. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application.
2. what are the job duties of mechanical engineer?                                                                       Mechanical engineers are work in with varies field on duties like research and development, design field in like develop a model and analyst of that model, develop, build, and test mechanical and thermal devices, including tools, engines, and machines.

Mechanical engineers typically do the following areas :

First of all Analyse all problems to see how mechanical and thermal devices help to solve the problem.

Design or redesign mechanical like  and thermal devices using analysis and computer-aided design.Develop and test prototypes of devices they design.Analyze the test results and change the design as needed.Oversee the manufacturing process for the device.

Mechanical engineers design and oversee the manufacturing of many products ranging from medical devices to new batteries. They also design power-producing machines such as electric generators, internal combustion engines, and steam and gas turbines as well as power-using machines, such as refrigeration and air-conditioning systems.

Like other engineers, mechanical engineers use computers to help create and analyze designs, run simulations and test how a machine is likely to work

The mechanical engineering field requires an understanding of core areas including mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity. In addition to these core principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product life cycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others. It is the branch of engineering that involves the design, production, and operation of machinery

Assignment Problem

Assignment Problem is a type of linear programming problem where the objective is to minimize the assignment cost or time of completing a number of jobs (activities) by a number of persons (resources) in such a way that only one resource is assigned to one activity It is known as a special case of transportation problem in which each source and destination will have unity capacity and requirement and also allocations are made on one to one basis.

Strain gauges:
An electrical-resistance strain gauge is a device for measuring normal strains (ɛ) on the surface of a stressed object. The gauges are small (less than 2 inch) made of wires tha are bonded to the surface of the object. Each gauge that is stretched or shortened when the object is strained at the point, changes its electrical resistance. This change in resistance is converted into a measurement of strain. From three measurements it is possible to calculate the strains in any direction. A group of three gauge arranged in a particular pattern is called a strain rosette. Because the rosette is mounted in the surface of the body, where the material is in plane stress, we can use the transformation equations for plane strain to calculate the strains in various directions.
