Preamble

To meet the challenge of ensuring excellence in engineering education, the issue of quality

needs to be addressed, debated and taken forward in a systematic manner. Accreditation is

the principal means of quality assurance in higher education. The major emphasis of

accreditation process is to measure the outcomes of the program that is being accredited. In

line with this Faculty of Science and Techn ology (in particular Engineering)of University of

Mumbai has taken a lead in incorporating philosophy of outcome based education in the

process of curriculum development.

Faculty resolved that course objectives and course outcomes are to be clearly defined for

each course, so that all faculty members in affiliated institutes understand the depth and

approach of course to be taught, which will enhance learner’s learning process. Choice

based Credit and grading system enables a much -required shift in focus fr om teacher -centric

to learner -centric education since the workload estimated is based on the investment of time

in learning and not in teaching. It also focuses on continuous evaluation which will enhance

the quality of education. Credit assignment for cou rses is based on 15 weeks teaching

learning process, however content of courses is to be taught in 12 -13 weeks and remaining

2-3 weeks to be utilized for revision, guest lectures, coverage of content beyond syllabus etc.

There was a concern that the earlie r revised curriculum more focused on providing

information and knowledge across various domains of the said program, which led to

heavily loading of students in terms of direct contact hours. In this regard, faculty of science

and technology resolved that to minimize the burden of contact hours, total credits of entire program

will be of 17 1, wherein focus is not only on providing knowledge but also on building skills, attitude

and self learning. Therefore in the present curriculum skill based laboratories and mini projects are

made mandatory across all disciplines of engineering in second and third year of programs, which will

definitely facilitate self learning of students. The overall credits and approach of curriculum proposed

in the present revision is in line with AICTE model curriculum.

The present curriculum will be implemented for Second Year of Engineering from the

academic year 2020 -21. Subsequently this will be carried forward for Third Year and Final

Year Engineering in the academic years 2021 -22, 2022 -23, respectively.

Incorporation and implementation of Online Contents from NPTEL/ Swayam

Platform

The curriculum revision is mainly focused on knowledge component, skill based activities and

project based activities. Self learning opportunities are provided to lear ners. In the revision process

this time in particular Revised syllabus of ‘C ‘ scheme wherever possible additional resource links

of platforms such as NPTEL, Swayam are appropriately provided. In an earlier revision of

curriculum in the year 2012 and 2016 in Revised scheme ‘A' and ‘B' respectively, efforts were

made to use online contents more appropriately as additional learning materials to enhance learning

of students.

In the current revision based on the recommendation of AICTE model curriculum overall credits are

reduced to 171, to provide opportunity of self learning to learner. Learners are now getting

sufficient time for self learning either through online courses or additional projects for enhancing

their knowledge and skill sets.

The Principals/ H oD’s/ Faculties of all the institute are required to motivate and encourage learners

to use additional online resources available on platforms such as NPTEL/ Swayam. Learners can be

advised to take up online courses, on successful completion they are requi red to submit certification

for the same. This will definitely help learners to facilitate their enhanced learning based on their

interest.

Preface

When the entire world is discussing about ‘Industry 4.0’, we are at the crossroads. There are so many

expectations from the graduating engineers, who shall be the major contributors to ecosystem for

development of the Nation. Engineering education in India, in general, is being revamped so as to

impart the theoretical knowledge along with industrial exposure. It is our attemp t, when we are

introducing a new curriculum; to bridge the industry -academia gap. To enable this, we have introduced

components such as skill -based laboratories and project -based learning. We trust that this will allow the

learner to apply knowledge gain ed in previous and current semesters to solve problems for gaining

better understanding. What once were pure mechanical systems have now been transformed into

multidisciplinary systems of mechatronics, electronics and computer science. Interdisciplinary

knowledge is gaining importance as we are moving towards automated world as technology advances.

Keeping this in mind the curriculum has been designed in a way so that learner shall be acquainted with

many Interdisciplinary subjects.

Engineers develop new t echnological solutions. During the engineering design process, the

responsibilities of the engineer may include defining problems, conducting and narrowing research,

analyzing criteria, finding and analyzing solutions, and making decisions. The Program Edu cational

Objectives for Undergraduate Program were finalized in a brain storming session, which was attended

by several faculty members and Industry experts. The Program Educational Objectives proposed for the

undergraduate program in Mechanical Engineerin g are listed below:

1. To prepare the stake holder to exhibit leadership qualities with demonstrable attributes in

lifelong learning to contribute to the societal needs.

2. To make ready the stake holder to pursue higher education for professional development

3. To help the stake holder to acquire the analytical and technical skills, knowledge, analytical

ability attitude and behavior through the program

4. To prepare the stakeholders with a sound foundation in the mathematical, scientific and

engineering fundamental s

5. To motivate the learner in the art of self -learning and to use modern tools for solving real life

problems and also inculcate a professional and ethical attitude and good leadership qualities

6. To prepare the stake holder to able to Design solutions for complex engineering problems and

design system components or processes that meet the specified needs with appropriate

consideration for the public health and safety, and the cultural, societal, and environmental

considerations.

We trust this revised versi on of syllabus come up to the expectations of all stakeholders. We trust this

revised version of syllabus come up to the expectations of all stakeholders. We wish to place on record

our sincere thanks and appreciations to the various contributors from the academia and industry for their

most learned inputs in framing this syllabus.

Guidelines for Mini Project

Students shall form a group of 3 to 4 students, w hile forming a group shall not be

allowed less than three or more than four students, as it is a group activity.

Students should do survey and identify needs, which shall be converted into

problem statement for mini project in consultation with faculty sup ervisor/head of

department/internal committee of faculties.

Students hall submit implementation plan in the form of Gantt/PERT/CPM chart,

which will cover weekly activity of mini project.

A log book to be prepared by each group, wherein group can record we ekly work

progress, guide/supervisor can verify and record notes/comments.

Faculty supervisor may give inputs to students during mini project activity;

however, focus shall be on self -learning.

Students in a group shall understand problem effectively , propose multiple solution

and select best possible solution in consultation with guide/ supervisor.

Students sh all convert the best solution into working model using various

components of their domain areas and demonstrate.

The solution to be validated w ith proper justification and report to be compiled in

standard format of University of Mumbai .

With the focus on the self -learning, innovation, addressing societal problems and

entrepreneurship quality development within the students through the Mini

Projects, it is preferable that a single project of appropriate level and quality to be

carried out in two semesters by all the groups of the students. i.e. Mini Project 1 in

semester III and IV. Similarly, Mini Project 2 in semesters V and VI.

However, based on the individual students or group capability, with the mentor’s

recommendations, if the proposed Mini Project adhering to the qualitative aspects

mentioned above gets completed in odd semester, then that group can be allowed

to work on the extension of the Mini Project with suitable

improvements/modifications or a completely new project idea in even semester.

This policy can be adopted on case by case basis.

Guidelines for Assessment of Mini Project:

Term Work

The review/ progress monitoring committee shall be constituted by head of

departments of each institute. The progress of mini project to be evaluated on

continuous basis, minimum two reviews in each semester.

In continuous assessment focus shall also be on each individual student,

assessment based on individual’s contribution in group activity, their

understanding and response to questions.

Distribution of Term work marks for both semesters shall be as below;

o Marks awarded by guide/supervisor based on log book : 10

o Marks awarded by review committee : 10

o Quality of Project report : 05

Review/progress monitoring committee may consider following points for

assessment based on either one year or half year project as mentioned in

general guidelines.

One-year project:

In first semester entire t heoretical solution shall be ready, including

components/system selection and cost analysis. Two reviews will be

conducted based on presentation given by students group.

First shall be for finalisation of problem

Second shall be on finalisation of propos ed solution of problem.

In second semester expected work sh all be procurement of

component s/systems, building of working prototype, testing and validation of

results based on work completed in an earlier semester.

First review is based on readiness of building working prototype to

be conducted.

Second review shall be based on poster presentation cum

demonstration of working model in last month of the said semester.

Half -year project:

In this case in one semester students’ group shall complete project in all

aspects including,

o Identification of need/problem

o Proposed final solution

o Procurement of components/systems

o Building prototype and testing

Two reviews will be conducted for continuous assessment,

First shall be for finalisation of problem and proposed solution

Second shall be for implementation and testing of solution.

Assessment criteria of Mini Project.

Mini Project shall be assessed based on following criteria;

1. Quality of survey/ need identification

2. Clarity of Problem definition based on need.

3. Innovativeness in solutions

4. Feasibility of proposed problem solutions and selection of best

solution

5. Cost effectiveness

6. Societal impact

7. Innovativeness

8. Cost effectiveness and Societal impact

9. Full functioning of working model as per stated requi rements

10. Effective use of skill sets

11. Effective use of standard engineering norms

12. Contribution of an individual’s as member or leader

13. Clarity in written and oral communication

In one year, project , first semester evaluation may be based on first six

criteria’s and remaining may be used for second semester evaluation of

performance of students in mini project .

In case of half year project all criteria’s in generic may be considered for

evaluation of performance of students in mini project.

Guideline s for Assessment of Mini Project Practical/Oral Examination:

Report should be prepared as per the guidelines issued by the University of

Mumbai.

Mini Project sh all be assessed through a presentation and demonstration of

working model by the student projec t group to a panel of Internal and External

Examiners preferably from industry or research organisations having experience of

more than five years approved by head of Institution.

Students shall be motivated to publish a paper based on the work in

Conferen ces/students competitions.
