A fluid in which the viscous stresses taken place from its flow at all the point are linearly proportional to the rate of change in its deformation over time is called Newtonian fluid. Newtonian fluid explains the relationship between the shear rate and the shear stress is linear with the proportionality constant, which is to be referred as the coefficient of viscosity. Non-Newtonian fluid is a fluid where the properties of fluid flow are not similar with Newtonian fluid. In Newtonian fluids,…

1) What are engineering stress and strain? Answer: Engineering Stress: Engineering stress is also called nominal stress, and it is defined as the applied load divided by the original cross sectional area of the material. Engineering Strain: Engineering strain is defined as the amount of material that deforms per unit length in a tensile test. Engineering strain is also known as nominal strain. 2) In the figure below, graphically show the toughness of three class materials:…

(a) Langmuir isotherm model Langmuir isotherm is based on the following assumptions: (a) each surface site can be singly occupied, (b) there are no lateral interactions between adsorbed species, (c) the enthalpy of adsorption is independent of surface coverage and (d) energy of adsorption is constant. The Langmuir isotherm is 2.5…

Experiment-1 Simple pendulum: Aim: The main aim of this simple pendulum experiment is to investigate the relationship between the time period of a simple pendulum (oscillation) and the effective length (total length) of the simple pendulum. The three variables in Experiment-1 Simple pendulum: Independent variable: The independent variable in this experiment is the length of the string of the pendulum that could be changed. Dependent variable: The dependent variable is the time period for one…

The purpose of this experiment was to understand kinetic and potential energy and verify the Law of Conservation of Energy. Kinetic and potential energy are both forms of energy that usually coincide with each other; potential energy usually changes into kinetic energy and vice versa. While potential energy results from an object’s position or arrangement of parts, kinetic energy results from an object’s motion. Together, the sum of an object’s kinetic energy and the potential energy at that…

Y-Component x- X-Component Mathematical Model Basic Equations: Force Equation (used to find the force of any given object): F=ma F-Net Force, m-mass, a-acceleration Summation of Forces on X-Axis: 〖ΣF〗^x=F^(G,x)-F^Sp 〖ΣF〗^x is the sum of the forces on the x-axis, denoted by the superscript x, and the x-axis follows the Free-Body Diagram above. F^(G,x) is the x-component of the Force of Gravity by the Earth on the cart. F^Sp is the Force of Spring on the cart. Hooke’s Law for Springs:…

For this plan I was given the challenge of finding a way to help the actors remember the order of the play and their entrance and exits. I wanted to push the actors to use the space and not have to use language to communicate. The challenge here was to create a plan that would be sustaining and challenging but not restricting to the Deaf actors by taking their language away from them. The intention of the workshop was to slowly over stimulate the actors so that they would start to multitask. By…

used. There are four forces acts on a train. One of them is its weight which balanced by the typical reaction of the tracks. The third one is the thrust force produced by the locomotives which move the train forward, and the fourth one is the combination of air resistance and the rolling friction between wheels and the railway tracks. There is another force called Centrifugal force act on a train when it takes turns. This force tends the train to run straight, but this force is overcome by the…

assumed to exist in the sticking and sliding regions, respectively[42]. Most analyses have applied classical friction situation following Coulomb’s laws which is based on coefficient of friction [e.g., [55], [62]]. Frictional sliding force F is proportional to the force N normal to the interface at which sliding is taking place. This model can be expressed by: However, the above equation fails to give accurate prediction in high normal stress conditions. Several studies applied modified Coulomb…

When society breaks down, death and destruction incur. In the book The Lord Of The Flies by William Golding the effects of the breakdown of society is a major theme. Humans identities are formed when society’s rules and laws are non existent, and humans are forced to rely off of their own morals. This can be seen when Ralph’s tribe is demolished by Jack because of Jack 's different ideology . In addition, Piggy’s logic and intelligence when talking about advanced topics on the island also show…
