Interview questions and answers


Mechanical Engineering Interview Questions and answers for freshers on design, safety and maintenance.
1) What is an accident ?
An accident is a unexpected and unforeseen event which may or may not injury to a person or a machine tool.
2) What are the standard sizes of drawing board as per Indian Standards?
As per Indian Standards :1250×900,900×650,650×500,500×350,350×250 sizes are available.
3) What are the functions of a scale ?
(a) To measure distance accurately.
(b) For making drawing to scale either in full size, reduced size or enlarged size.
4) What is a sketching ?
This is freehand expression of the graphic language.
5) What do you mean by First Aid ?
First Aid is immediate and temporary care given to a person who affected accidental injury or a sudden illness before the arrival of doctor.
6) What is a Drawing ?
It is a graphical representation of a real thing to define and specify the shape and size of a particular object by means of lines.
7) What is Engineering Drawing ?
A drawing which is worked out an engineer for the engineering purpose is known as Engineering Drawing.
8)  What are the methods of extinguishing fire ?
1) Starvation. Separating or removing the burning material from the neighbour hood of the fire.
2) Blanketing. Preventing the air flow to the fire.
3) Cooling. Lowering the heat created by burning materials.
9)  What are the precautions to be taken to avoid fire ?
1) The buckets along with sand should be placed inside the workshop.
2) Switches and other electrical parts must be made of fireproof material.
3) Carbon dioxide gas should be place at required points in special containers.
4) Fire extinguishers of suitable type should be placed at accessible places.\
10) What safety precautions should be observed while working in the workshop ?
1) Keep shop floor clean, free from oil and other slippery materials.
2) Wear proper dress and avoid loose clothing and loose hair.
3) Wear shoes and avoid chapels.
4) Avoid playing, loose talk and funning inside the shop floor.
5) Keep good housekeeping and put all unnecessary items and rejected items in scrap box.
6) Learn everything about the machine before starting and clear all the doubts.
7) Keep a safe distance from rotating and sliding parts.
8) Never store inflammable materials inside or around the shop.
9) Never play with electricity, fire, parts with sharp edge etc.
10) Keep fire buckets and extinguishers ready for use.

Bevel protractor

What is bevel protractor ? A bevel protractor is a graduated circular protractor with one pivoted arm used for measuring or marking off angles. Sometimes Vernier scales are attached to give more precise readings. It has wide application in architectural and mechanical drawing, although its use is decreasing with the availability of modern drawing software or CAD. Universal bevel protractors are also used by toolmakers, as they measure angles by mechanical contact they are classed as mechanical protractors. The bevel protractor is used to establish and test angles to very close tolerances. It reads to 5 minutes or 1/12° and can measure any angle from 0° to 360°. The bevel protractor consists of a beam, a graduated dial and a blade which is connected to a swivel plate (with Vernier scale) by thumb nut and clamp. When the edges of the beam and blade are parallel, a small mark on the swivel plate coincides with the zero line on the graduated dial. To m...

Turbines

You all know about turbines, here is a brief view of turbines. What actually turbine is :   A  turbine  is a turbo machine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. A windmill is the simplest kind of turbine: a machine designed to capture some of the  energy  from a moving fluid (a liquid or a gas) so it can be put to use. As the wind blows past a windmill's sails, they rotate, removing some of the wind's  kinetic energy  (energy of movement) and converting it into mechanical energy that turns heavy, rotating stones inside the mill. The faster the wind blows, the more energy it contains; the faster the sails spin, the more energy is supplied to the mill. Adding more sails to the windmill or changing their design so they catch the wind better can also help to capture more of the wind's energy....

Competitions for mechanical engineers

There are various competitions in which you can participate during your graduation. SAE (society of automative engineers) organize three major events every year :  1. BAJA SAE- design and build an all terrain vehicle 2. SUPRA SAE- design and build a formula type race car 3. EffiCycle- design and build a hybrid cycle ASME  ( american society of mechanical engineers) organize human powered vehicle challenge HPVC. ISNE - It organizes go karting championship. If you have interest in automobiles then these competitions will definitely helps you to improve your skills.I was participated in SUPRA SAE (2016).It was a cool experience for me and helps me to improve my basic knowledge.
