Computer Oriented Numerical Analysis
What is interpolation?
Many times, data is given only at discrete points such as .
So, how then does one find the value of y at any other value of x ?
Well, a continuous function f(x) may be used to represent the data values with f(x) passing through the points (Figure 1). Then one can find the value of y at any other value of x .
This is called interpolation
Newton’s Divided Difference Formula:
To illustrate this method, linear and quadratic interpolation is presented first.
Then, the general form of Newton’s divided difference polynomial method is presented.

Vector Addition of Forces
Objectives: To use the force table to experimentally determine the force that balances
two or more forces. This result is checked by analytically adding two or more forces
using their horizontal and vertical vector components, and then by graphically adding
the force vectors on the force table.
Theory: If several forces are acting on a point, their resultant 𝑅 is given as
𝑅 = 𝐴 + 𝐵 + 𝐶
Rx = Ax + Bx + Cx
Ry = Ay + By + Cy
R = 𝑅 = 𝑅!! + 𝑅!!
𝜃! = tan!!
𝑅!
𝑅!
Then if the equilibrant 𝐸 is a force that brings the system to equilibrium
E+ 𝑅 = 0, this means
𝐸 = −𝑅 (E = R, θE = θR+180°)
This means Ex = -Rx and Ey = -Ry
Note for today’s lab: read the details, discuss with your group, and follow the
instructions systematically. We have done several of these questions in class so now
work by yourselves. If you want more details, look up your textbook or online.
Method: You will hang some mass on the pulley hangers that are attached by a thread.
This means the weight of that mass is a force vertically down. However, the string is
attached to the central ring of the force table, and this means a tension equal to the
weight of the mass is a force acting on the central ring. This means you can set up one
or more forces acting on the central ring, calculate their resultant force (resultant, 𝑅).
Then you can determine what force (Equilibrant, 𝐸) would balance these forces to bring
the system to equilibrium.
Apparatus:
Force table, 4 pulley clamps, 3 mass hangers, 1 mass set, string (or spool of thread)
Force table: A force table is a simple set up that can be used to observe vector addition
and equilibrium. You can attach a (one or more) pulley at the edge of the table, and
hang a mass on a string that goes through this pulley. Hanging mass means a weight is
2
acting downward and the tension on the hanging string is acting upward. However, on
the top of the table, the string is attached to a central ring. This string applies a
horizontal tension to the ring. The central ring is our object of interest and we will
observe the effect of various forces on this ring. You can change the magnitude of the
force by changing the hanging mass.
The table surface has a protractor so you can set up vectors in specific directions.
You can find more information online on how a force table works.
If a mass “m” is hanging over the pulley, the mass has a force downward (= the weight
of the mass, mg). And the tension on the string is upward. The magnitude of the tension
= mg)

Set up the force table such that 0 of the table protractor is on your right (just like x-axis
on a Cartesian coordinate system. This means 0°, 90°, 180°, and 270° should be along
+x, +y, -x, -y of your coordinate system.

Resultant vs. Equilibrant
Resultant force is the vector sum of the individual forces
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

14. Weight (Newtons) Stretch (meters) Stretch Versus Weight If there is a general trend to the data, then a best-fit curve describing this trend can be drawn. In this example the data points approximately fall along a straight line. This implies a linear relationship between the stretch and the weight. 0 10 20 30 40 50 60 0.10 0.14 0.18 0.22 0.26 0.30
15. Weight (Newtons) Stretch (meters) Stretch Versus Weight Important information can be obtained if we know the equation that describes the data.
