Single parents have it hard from balancing day to day life, to handling a full-time job, balancing financial needs, making sure their children are taking care of which are just the basic needs that a single parent does. Many single parents take that leap of going back to school to better and secure their future for their family. However, single parents that make the choice of going to back to school to better themselves go through a lot of issues or self-neglect. Because of the self-neglect and the

College life can be extremely stressful, especially for freshmen. However, it’s not just freshman that can be can be affected by stress, no one on earth is immune to stress. Stress is the body’s way of reacting to physical demand around it. Stress occurs when the bodies tension levels rise, exceeding one’s tension level causing the person to feel stressed and overloaded. Stress can be caused by many things, and college students have been known to be more susceptible to stress; especially in their

calculate the modulus of elasticity (Young’s Modulus) or E of the cantilever beam. Through the course of the experiment our observations revealed that the addition of weights deformed the beam in response to the applied stress. This deformation can be modeled using the Euler-Bernoulli beam bending theory. Our experimentation and calculations revealed that our data did indeed prove the theories mentioned in this lab. Furthermore, our values for the modulus of elasticity or E came within the range

The Cauchy stress principle is one of the main hypotheses in mechanics of solids. The study of linear and nonlinear wave processes is very important. Elastic waves are high-performance instrument to research strained and deformed state of solids an also to study their structure and properties. Elastic waves can propagate deeply inside the material without disturbing the material state. The elasto-dynamic problem is a challenging predicament to the modern material scientists. In the last twenty years

INTRODUCTION: The study of large deflection of cantilever beam comes from theory of elasticity. Theory of elasticity state that “solid material will deform under the application of an external force it will again regain their original position when external force is removed is referred to as elasticity”. We took beam made of nickel titanium alloy which regain their original shape after removing external force act on the beam. It’s a prismatic circular cross section

Gel hydrogels can be considered as promising materials to be used as scaffold in tissue engineering since they present a load-bearing capacity and suitable mechanical properties.6 Almost all the measurements on the mechanical properties of hydrogel materials have used true stress-true strain or engineering stress-engineering strain definitions on the grounds of hydrogel incompressibility.26 However, there is no agreement as to which stress-strain definition should be adopted to determine the mechanical

Chapter One INTRODUCTION AND LITERATURE REVIEW 1.1 INTRODUCTION Pipe bends are used in power plants, oil refineries, petroleum pipelines, chemical industries, pharmaceuticals and food industry. The main purpose of bend pipe is to change the direction of substance in the piping system and it is considered as one of the critical components in the piping systems due to its flexibility. The piping system carry substances from one point to another point. The carrying of substance in pipe system will be

is described in Chapterfour. This geological model was then input into the VISAGE geomechanical software package and each geological cell was converted into a finite element. The VISAGE package solves the state of stress equations assuming linear elasticity using the finite element method. The stress tensor is a second order symmetric tensor then it
