systems all forces and torques sum to zero. In problems where the first and second conditions of equilibrium are satisfied‚ the best strategy is to create FBD’s for both the first and second conditions‚ derive equations based on these FBD’s and then see what useful information may be gleaned from these equations. When applying the second condition we are free to choose any axis about which to compute torques. It is best to choose an axis that eliminates one or more forces that have lines of force that pass

Donald Trump’s Twitter account was the target of a "rogue" employee who apparently is not a fan of the president. In a Friday tweet storm in response to the outage incident‚ Trump gave a "Covfefe"-esque response as to the worker’s motivation. In what is mystifying to some on Twitter‚ the POTUS said his account was sabotaged because his messages were "finally getting out... and having an impact." https://www.inquisitr.com/4595893/trumps-twitter-account-down-update-hero-employee-sabotaged-potus-account-last-day-on-job/

Six Forces Porter’s forces analysis is a framework for industry analysis and business strategy development that draws upon industrial organization economics to determine the competitive intensity and overall industry profitability. These forces are 1) potential entry of new competitors‚ 2) bargaining power of suppliers‚ 3) bargaining power of buyers‚ 4) substitute products‚ 5) rivalry among competing sellers in an industry‚ and 6) power of stakeholders. A change in any of the forces normally

Addition of Force Vectors Abstract The purpose‚ of this experiment‚ was to prove that there is a relation between the magnitude of the resulting vector‚ and the angle between the vectors that are being added. The test was performed by creating a balance between three weights tied to strings on a pulley that transferred the string on top of a graduated disc‚ which made easy the measurement of the angles between them. After performing the experiment‚ my group concluded that there is a relation

The Four forces of Evolution Evolution is divided into two categories macroevolution and microevolution; macroevolution focuses on the formation of a new species‚ while microevolution focuses on the change in allele frequencies in a population (47). The process of evolution has four forces‚ mutation‚ gene flow‚ genetic drift‚ and natural selection. Evolution is caused by the isolation of populations which leads to variation and eventually speciation. A population is a group of individuals within

Through his use of imagery and soliloquies‚ he is able to convey the key ideas from his play to the audience in an engaging composition. His play is based around important forces that mould the events whilst unravelling the storyline in a tense and complex manner. The forces I discuss are fate‚ hate and love. Fate is a powerful force in the play of Romeo and Juliet where the events of the two characters were heavily influenced. In William Shakespeare’s tragedy‚ both Romeo and Juliet are subject to

horrifying experience of a gas attack in World War I. Owen goes into excruciating detail on every effect of the gas‚ and describes almost everything about the physical state of the infected‚ dying man. Thousands of soldiers were exposed to gas in the war‚ and unfortunately‚ many of them died from the effects. The first attack that the Germans unleashed on the allies was devastating. Over 5000 soldiers were killed with many more incapacitated (Christianson 30). While the attack was detrimental to the strength
