In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

Friction. Do you know what is friction and how it plays different roles in our general life. There are many section in our life where friction is necessary like - in playing sitar and guitar, walking on the road and to hold something in our hand or in any mechanical devices. But there are many field where friction is not required like - in machines where two surfaces meet at a point. Due to this the life of the machine parts get decreased and failure may be occur there. Know more about different laws of friction, types of friction, elimination of the friction.
Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

3. Force System
If all the forces in a system lie in a single plane through a single
point, they constitute a coplanar concurrent force system. it is
possible to find a single force which will have the same effect as
that of number of force acting. Such single force is called
Resultant force and the process of finding the resultant force is
called composition of forces.
December 31, 2016 RAVI VISHWAKARMA
4. Force
1) Force is a push or pull.
2) Force is the capacity to do work or cause physical
change.
3) Force= Mass times acceleration (F = ma)
4) A force is that which changes or tends to change the state
of rest or motion of a body.
December 31, 2016 RAVI VISHWAKARMA
5. Law of Parallelogram
This law is applicable to determine the resultant of two
coplanar concurrent forces only. This law states ―If two
forces acting at a point are represented both in magnitude
and direction by the two adjacent sides of a parallelogram,
then the resultant of the two forces is represented both in
magnitude and direction by the diagonal of the
parallelogram passing through the same point.”
December 31, 2016 RAVI VISHWAKARMA
7. Collinear forces
Forces have the same line of action.
May act in same or different directions.
December 31, 2016 RAVI VISHWAKARMA
8. Collinear forces
Forces have the same line of action.
May act in same or different directions.
December 31, 2016 RAVI VISHWAKARMA
9. Concurrent Forces
Forces do not act along same line, but do act through
the same point.
In physics, concurrent forces are defined as forces that
pass through a common point.
In other words,
a concurrent force system is a set of two or
more forces whose lines of action intersect at a point
at the same time.

10. Lami’s Theorem
If a body is in equilibrium under the action of only three
forces, each force is proportional to the sine of the angle
between the other two forces.

11. Principle of Transmissibility
States that the conditions of equilibrium or conditions of
motion of a rigid body will remain unchanged if a
force acting at a give point of the rigid body is
replaced by a force of the same magnitude and same
direction, but acting at a different point, provided that
the two forces have the same line of action.
December 31, 2016 RAVI VISHWAKARMA
12. Moment of Force
Moment of force about a point is the measure of rotational
effect of the force. Moment of a force about a point is
defined as the product of the magnitude of the force and
the perpendicular distance of the point from the line of
action of the force. The point about which the moment is
considered is called moment center and the perpendicular
distance of the point from the line of action of the force is
called moment arm.

13. Couple
A couple is a pair of forces, equal in magnitude,
oppositely directed, and displaced by perpendicular
distance or moment.
The simplest kind of couple consists of two equal and
opposite force whose lines of action do not coincide.
This is called a "simple couple". The forces have a
turning effect or moment called a torque about an
axis which is normal (perpendicular) to the plane of
the forces. The SI unit for the torque of the couple
is newton meter.

14. Varignon’s theorem
French mathematician Varignon(1654-1722) gave the
following which is also known as principles of moments:
The algebraic sum of moments of a system of coplanar
forces about a moment center is equal to the moment of
their resultant force about the same moment center.
December 31, 2016 RAVI VISHWAKARMA
15. Resolution of force
Finding the components of a given force in two given
direction is called resolution. These component forces will
have the same effect on the body as given single force.

16. Resultant of coplanar –Concurrent forces
The analytical method is based on theorem of resolved
parts which states that
“ The algebraic sum of the resolved parts of two forces
in a given direction is equal to the resolved part of
their resultant in the same direction.”

18. Free Body Diagram
The force analysis of a structure is made in a simplified way
by considering the equilibrium of a portion of the
structure. For that, the portion is drawn separately
showing applied forces, self weight and reactions at the
point of contact with other bodies. The resulting diagram
is known as free body diagram.
In a FBD, all the supports (like walls ,floors, hinges etc) are
removed and replaced by the reactions which these
supported exert on the body.
Examples-…….

19. Center of Gravity
• The point at which all the mass of the body may be assumed to
be concentrated.
• The point through which the force of gravity is considered to
act vertically downwards, with a force equal to the weight of
the body. The point about which the body would balance. The
center of gravity of a homogeneous body is at its geometrical
center.

20. Centroids
The centroid of an area is situated at its geometrical centre. In
each of the following figures ‘G’ represents the centroid, and if
each area was suspended from this point it would balance.

21. Moment of Inertia
The product of the elemental area and square of the
perpendicular distance between the centroid of area and the
axis of reference is the “Moment of Inertia” about the reference
axis.
