THEORY OF MACHINES FOR VTU, AMIE, DME STUDENTS..
The study of a mechanism involves its analysis as well as synthesis.
Analysis is the study of motions and forces concerning different parts
of an existing mechanism. Whereas Synthesis involves the design of its
different parts.
Mechanics: It is that branch of scientific analysis which deals with
motion, time and force.
Kinematics is the study of motion, without considering the forces
which produce that motion. Kinematics of machines deals with the
study of the relative motion of machine parts. It involves the study of
position, displacement, velocity and acceleration of machine parts.
Dynamics of machines involves the study of forces acting on the
machine parts and the motions resulting from these forces.
Plane motion: A body has plane motion, if all its points move in
planes which are parallel to some reference plane. A body with plane
motion will have only three degrees of freedom. i.e., linear along two
axes parallel to the reference plane and rotational/angular about the
axis perpendicular to the reference plane. (eg. linear along X and Z
and rotational about Y.)The reference plane is called plane of motion.
Plane motion can be of three types. 1) Translation 2) rotation and 3)
combination of translation and rotation.
Translation: A body has translation if it moves so that all straight
lines in the body move to parallel positions. Rectilinear translation is a
motion wherein all points of the body move in straight lie paths.
Eg. The slider in slider crank mechanism has rectilinear translation.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

PROCEDURES
● GENERAL CONSIDERATIONS IN MACHINE
DESIGN
3. 1. INTRODUCTION
➔ A new or better machine in one which is more economical in the overall
cost of production and operation. The process of design is a long and
time consuming . From the study of existing ideas , a new ideas has to be
conceived . In the preparation of these drawings care must be taken of
the availability of resources in money in men and in materials required
for the successful complition of the new idea into the actual reality. In
designing a machine component , it isnecessary to have a good
knowledge of many subjects SOM , TOM , WORKSHOP PROCESSS , AND
ENGINEERING DRAWING.
4. CLASSIFICATION OF MACHINE DESIGN :
1. ADAPTIVE DESIGN
2. DEVELOPMENT DESIGN
3. NEW DESIGN
● RATIONALDESIGN
● EMPIRICAL DESIGN
● INDUSTRIAL DESIGN
● OPTIMUM DESIGN
● SYSTEM DESIGN
● ELEMENT DESIGN
● COMPUTER AIDED DESIGN
5. GENERAL CONSIDERATION OF MACHINE DESIGN:-
Following are the general consideration in designing a
machine component:-
1. Types of load and stressescaused by the load
2. Motion of the parts or kinematics of the machine
3. Selection of materials
4. Form and size of the parts
5. Frictional resistance and lubrication
6. Convenient and economical features
7. Use of standard parts
8. Safety of operation
9. Workshop facilities
10.Number of machine to be manufactured
7. 1. Types of load and stresses caused by load:-
The load on a machine component may act in several ways due to which the
internal stresses are set up.
2. Motion of the parts or kinematics of the machine:-
The successful operation of any machine depends largely upon the simplest
arrangement of the parts which will give the motion required.
The motion of the parts may be:-
● Rectilinear motion which include unidirectionaland reciprocating machine.
● Curvilinear motion which includes rotary , oscillatory and simple harmonic.
● Constant velocity.
● Constant and variable acceleration.
8. 3. Selection of materials:-
It is essential that a designer should have thorough knowledge of the properties of
the material and their behaviour under working conditions.some of the important
characteristics of materials are : strength , durability , flexibility , weight , resistance to
heat and corrosion , ability to cast welded or hardened , machinability , electrical
conductivity etc . the various types of engineering materials and their properties are
discussed above.
4. Form and size of the parts :-
The form and size are based on the judgement . the smallest practicable cross
section may be checked that the stress induced in the designed cross section are
reasonably safe. In order to design any machine part for form and size , it is
necessary to know the forces which the part must sustain. It is also important to
anticipate any sudenly applied or impact load which may cause failure.
9. 5. Frictional resistance and lubrication :-
There is always a loss of power due to frictional resistance and it should be the matter
of lubrication of all surfaces which move in contact whith others , weater in rotating ,
sliding, or rolling ,bearing.
6. Convenient and economical features :-
In designing, the operating features of the machine should be carefully studied, the se
Tarting , controlling and stopping livers should be located on the basis of convenient
hendling.
7. Use of standard parts :-
The use of standard parts is closely related to cost , because the cost of standerd or
stck parts is only a fraction of the cost of similar parts made to other.
10. 8. Safety of operations :-
Some machines are dangerous to operate , especially those which are speeded up to
insure production at a maximum rate . therefore , any moving part of machine which is
within the zone of a worker is considered on accident hazard and may be the cause of
an injury.
9. Workshop facilities :-
A design engineer should familiar with the limitations of his employers workshop , in
order to avoid the necessity of having work done in some other workshop.
10. Number of machines to be manufactured :-
The number of articles or machines to be manufactured affects the design in a
number of ways . the engineering and shop costs will are called fixed charges or
overhead expense are distributed over the number of articles to be manufactured .
11. 11. Cost of construction :-
The cost of construction of an article is the most important consideration involved in
design . in some cases , it is quite possible that the high cost of an article may
immediately bar it from further considerations . if an article has been invented and tests
of hand made samples have shown that it has commercial value , it is then possible to
justify the expenditure of considerable sum of memory in design and development of
automatic machines to produce the article , especially if it can be sold in large
numbers.
12. Assembling :-
Every machines or structure must be assembled as a unit before it can function large
units must often be assembled in the shop , tested and them taken to be transported to
their place of service .
12. General procedure in machine design:-
In designing a machine compartment , there is no rigid rule. The problem may
be attempted in several ways. However, the general procedure to solve a
design problem is as follows:-
1. Recognition of need :- first of all, make a complete statement of the
problem, indicating the need, aim or purpose for which the machine is to
be designed.
2. Synthesis (mechanism) :-select the possible mechanism or group of
mechanisms which will give the derived motion.
3. Analysis of force :- find the forces acting on which number of the
machine and the energy transmitted by each member.
4. Material selection:- select the material best suited for each member of
the machine.
5. Design of elements(size and stresses):- find the sizes of each member of
the machine by considering the force acting on the member and the
13. Permissible stresses for the material used . it should be kept in mind that each
member should not deflect or deform than the permissible stress.
6. Modification :- modify the size of the member to agree
with the post experiance and judgement to facilitate
manufacture. The modification may also be necessary by
consideration of manufacturing to reduce overall cost.
7. Detailed drawing :- draw the detailed drawing of each
component and the assembly of the machine with
complete specification for the manufacturing processes
suggested.
8.production :- the component as per drawing is
manufactured in workshop.
