COMPARISON OF L - SCHEME SYLLABUS WITH K - SCHEME SYLLABUS
STRENGTH OF MATERIALS
The title of the subject is changed from Mechanics of Materials to Strength of Materials considering
the contents of the syllabus and various book titles of different authors.
Strength of material is the backbone for design. The strength of material deals generally with the
behaviour of objects, when they are subjected to forces.
FLUID MECHANICS AND FLUID POWER
The main objective of this subject Fluid mechanic and Fluid power is to study the behavior of fluids
under the condition of rest and motion. This chapter deals with fluid pumps, turbines, hydraulic and
pneumatic operation. The overall objective is to impart knowledge of pumps (which play a major role
in day today life) hydraulic & pneumatic operation of tools & equipments.
THERMAL ENGINEERING-I
The growth of industries in the areas of Automobile and thermal power generation is the
contemporary need of the present day. For these industries Knowledge on the concept of
Thermodynamics, Thermodynamic Processes, Steady flow energy equation and study of fuels, IC
Engines and performance of IC Engines are vital.
MACHINE DRAWING
Manual Drafting and Computer Aided Drafting are given as two separate subjects. Machine Drawing
is carried out by the students by Manual drafting.
In K-Scheme Manual Drafting and Computer Aided Machine Drawing were being provided in the
same subject and learning was found to be difficult.
Manufacturing of various machine parts and production of various equipments in small scale to big
scale industries start from the basic drawing of components. The assembly of components is also
carried out from the drawing. So drawing is an important subject to be studied by supervisor cadre
students to carry and complete the production and assembly process successfully.
MECHANICAL TESTING & QUALITY CONTROL PRACTICAL
In K-Scheme only testing of materials alone were studied such as tensile strength, compressive
strength, shear strength etc.
In L-Scheme in addition to the above Microscopic structure of metals using metallurgical microscope
and quality of metals (crack & defect detection) are also included.
FLUID POWER PRACTICAL
In K-Scheme Fluid Mechanics experiments were studied as a part of Mechanics of Materials and
Fluid Mechanics Lab with little focus on Fluid Power.
In L-Scheme Fluid Power Practical is being introduced comprising of pneumatic exercises(low cost
Automation) and Oil Hydraulics considering the trend of industries towards fluid power.
MANUFACTURING TECHNOLOGY - I
In K-Scheme the title of the subject was “Manufacturing Processes” where as in L-Scheme it has
been changed to Manufacturing Technology-I
Manufacturing, the major and the most important aspect in industries needs utmost care and
attention. Knowledge about casting processes and allied areas will be of great use to the personnel
involved in production.
The areas like heat treatment, powder metallurgy and knowledge in centre lathe and special purpose
lathes will provide the students an opportunity to train themselves with the skills needed for the
present day industrial scenario.
RENEWABLE ENERGY SOURCES
Electrical Energy requirement is the major crisis and hence any saving in Electrical energy is
equivalent to production of Electrical Energy. Saving can be achieved by the utilization of Renewable
Energy Sources.
Hence in L-Scheme a new Subject on Renewable Energy Sources is being introduced covering Solar
Energy, Wind Energy, Bio Energy, Geothermal Energy etc.
ELECTRICAL DRIVES AND CONTROL
In K-Scheme the title of the subject was “Electrical & Electronics Engg.” covering the fundamentals.
In L-Scheme the title of the subject has been changed to Electrical Drives and Control considering the
application requirements of the Mechanical Engineer.
The subject aims in introducing the basic electrical DC and AC circuits and motors and also focuses
on the various special control devices like stepper, servo drives and its controlling elements.
COMPUTER AIDED MACHINE DRAWING PRACTICAL
Manual Drafting and Computer Aided Drafting are given as two separate subjects.
The contemporary progressing world is fast with the latest production systems. The advanced
manufacturing of products is developed instantly using CAD Software. Even a small scale industry is
now using a CAD software as it has become the heart of the Design department. So CAD has now
become inevitable in industries.
Accuracy and Precision are the two important things that decide the quality of a product to survive its
competitors in the market. Using CAD software design, the uniform accuracy, multiples of copies and
storing in a small space for long time are assured.
The CAD software considerably improves the creativity and flexibility of a designer. The syllabus here
enables a candidate to draw an industrial drawing within the optimum reach of a Diploma cadre.
MANUFACTURING TECHNOLOGY – I PRACTICAL
In K-Scheme the title of the subject was “Workshop - I” where as in L-Scheme it has been changed to
Manufacturing Technology-I Practical. In L-Scheme it includes skill training on Foundry, Welding and
Lathe.
The exercises in lathe are logically arranged so that the output of one exercise becomes the input
(Raw Material) for the next exercise. Thus Raw material can be saved and preservation of finished
jobs becomes easier.
METROLOGY & MEASUREMENT AND MACHINE TOOL TESTING PRACTICAL
In K-Scheme the title of the subject was “Metrology, Machine Tool Maintenance and Testing Lab”
was offered as an Elective subject.
In L-Scheme considering the significance of this subject “Metrology & Measurement and Machine

NOTES OF GUIDANCE
Role of the media:
To equip a learner with vocabulary, particularly active vocabulary and standard everyday
expressions ,using English dailies and watching selective English T.V. channels both in
the classroom and outside the classroom is focused. Such a provision is recommended
for the students to establish familiarity with the English dailies and selective English T.V.
channels.
Minimum two copies of two English dailies in the laboratory room (students can bring
their own copies also).Minimum two systems with net connection for information
collection in the laboratory itself.
Synopsis of the news item:
During every lab work day, students must choose a news item from the English
daily or weekly or monthly, and write a synopsis of the chosen news item, in not more
than five lines. The news item should be pasted on the left page and synopsis on the
right page (the chosen news item should not be politically, socially or communally
controversial). Students should exercise care in choosing the news items. Teachers
have to advise them on this aspect. This can be done outside the class hours also but
every record exercise should begin with the synopsis of news item of the date of the lab
session.
For example, first lab exercise namely departmental vocabulary and antakshari
is performed on 15/12/2011. The student should choose a news item from any English
daily of 15/10/2011 and record the synopsis on the right page (in not more than 5 lines)
under the caption Synopsis of the news item of the day/date 15/10/2011.There is no
harm in repeating or copying the lines form the passage. The essence of the passage
should be there. The cutout news item for presenting the synopsis should be pasted on
the left page of the record notebook.
This is to be done with interest for developing one’s personality. This work does
not carry any marks but without which the record exercise should not be valued. This is
the precondition for valuing the record exercise. Each record exercise follows the
synopsis of the chosen news item.
At the bottom of the synopsis, the student should record the dictionary meaning
of atleast one strange word found in the chosen news item. At the end of every month,
a minimum of 10 Headlines of 10 different days i.e. one Headline a day from anyone
English daily should be pasted on the right or left page of the Record Note Book. (This
work does not carry marks but this is the precondition for marking the record exercises)
External examiner, before signing the record notebook, should verify whether the
Newspaper works were recorded/pasted in the record notebook.
Verbal communication in any language begins with sounds in isolation, union and
word formation. Learning everyday words and expressions is the primary factor.
Grammar comes next. One can enrich one’s every day vocabulary by reading English
magazines and listening to or watching an English channel on television. So an English
laboratory should be equipped with a minimum of two copies of two English dailies and
English weeklies or monthlies.
Watching English channels helps the students improve their vocabulary and
expressions. If there is a provision, students may be permitted to watch selective, mind
corruption free English channels (sports, education, news, animal channels and so on)
for at least 15 min. during the English lab sessions. This will serve as motivation for the
students and help them shed their inhibition.
What is antakshari? (Polar word game)
This game can be played on the stage by two or three students using the departmental
words. Suppose Mr. A belongs to Dept.of Electrical and Electronics and he says his
departmental word ‘ ampere ‘Mr. B has to supply a word beginning with the ending letter
of Mr. A’s word. The word ampere ends with the letter ‘ e’ so Mr. B says ‘ electrical
‘.Mr. A has to continue with the letter ‘ l ’. Like that five pairs of words are to be
spoken.(Letter ending only, not sound ending. ) Suppose departmental words are not
available in some English letters like
‘ x ‘ ‘ y ‘ ‘ z ‘ the students may be permitted to use common words.

inter polytechnic or intra polytechnic competitions, sports activity, forums like NCC,NSS,
hobby, ambition, strengths and weaknesses.
Introducing others – merits – credentials—one or two points on his family.
Vote of thanks / Welcome address.No doubt it should be all-covering but Focus should
be on the important persons/invitees/chief guest and the message of the speaker.

projector or Magazine cuttings may be used. Just five lines on the picture will do.
Auditory/oral comprehension: A Passage from any English daily of the week of the
examination is to be read out for two to three minutes in the end examination. Display of
recorded passages can be used as an addition in the class room. The use of prerecorded passage discouraged in the end examination.

internet for collecting information on the topic, noting keywords and use them in their
presentation in his own language. One must be able to talk extempore for 2 min on any
topic, given a time of two minutes for organizing his/her thoughts. The topics can be kept
simple and general (current events of interest like sporting event for headline of the
day). It must be totally an oral activity without the aid of any other media.

daily of the week of the conduct of Examination is to be given. The caption may be a

Pl.note: Suppose departmental words are not available in some English letters like
‘ x ‘ ‘ y ‘ ‘ z ‘ the students may be permitted to use common words. This is only an
example. Another student of Mechanical Engineering can have different sets
of words under each letter of the English alphabet.Like that there may be
variety of sets. The most important point is that One is not supposed to
murmur but speak the words intelligibly in an audible manner. Swallowing the
words will deprive a student of winning a selection in an interview. In the
same way, students of other Departments can have different sets of words of
their departments under each letter of the English alphabet.
