The plot of the 2003 movie “The Core” is centered on the apparent ceasing of the core’s rotation and the ensuing catastrophes that threaten to obliterate life on earth within a year’s time. (more…)

Any thing whose particles can move easily from one place to another that means shape can be easily changed upon the application of negligible force. MECHANICS: Study of response of bodies upon the application of force. FLUID MECHANICS : Fluid mechanics may be defined as …

It is a ranking of the 100 people who, according to Hart, most influenced human history. [2] The first person on Hart’s list is the Prophet of Islam Muhammad. [3] Hart asserted that Muhammad was “supremely successful” in both the religious and secular realms. He …

Imagine a world with no concept of gravity, a world that knows not what forces affect a moving body, a world that does not understand the science affecting light and a world without calculus.  Imagine a world without one of its greatest minds, Sir Isaac …

How is inner and outer conflict represented in ‘Romeo and Juliet’ and ‘the charge of the light Brigade’? Whereas ‘Romeo and Juliet’ contains a lot of inner conflict as well as outer conflict, Lord Tennyson’s ‘Charge of the light Brigade’ contains many techniques to enhance …

Aim The main intention of this investigation was to determine the various stages of the Atterberg Limits. These included the liquid limit test (LL), plastic limit test (PL), plastic index test (PI), and linear shrinkage (LS) of a soil sample provided by the administration. This …

Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in …

Developing countries are countries with non- or undeveloped industrial base, low living standards, and low HDI (Human Development Index) compared to developed countries like the United States and the European Union countries. Morocco is a good example of a typical developing country. It has an …

Although many critics consider Cormac McCarthy to be the greatest living novelist in America, his dark, compelling vision did not reach a mass audience until the film adaptation of his novel No Country for Old Men (2005) was released in 2007. The film, directed by …

Introduction The bright line spectrum is the range of colorful lights that are emitted from an atom in its excited state. A “normal” atom, or an atom in its ground state, is when all of the atom’s electrons are in their proper energy level. When …

This literature study is based on active quiver control and its technology importance in systems ( mechanical ) . Active quiver control is the procedure of minimizing, insulating or rarefying forces imposed by quiver, by actively using opposing forces in order to acquire a desirable …
