Figure 2: Stress- strain graph The stress strain relation dependent on time and time-depending behavior of materials is known as visco-elasticity. This term derived in two expressions: Viscosity and Elasticity, Elasticity is about solid whereas Viscosity resistance to flow in fluids. Therefore, this type of material is a combination of fluid and solid properties which presents a following relation

Abstract: The main aim of the paper is to analyse the strength of bridge piers using accelerometers /vibration sensors .The capability of this sensor system is to analyse the property of the bridge pier remote end. It The development of low-cost wireless sensor networks has resulted in resurgence in the development of ambient vibration monitoring methods to assess the in-service condition of highway bridges. INTRODUCTION Bridges are a most significant part of daily life. They can save hours in traveling

Stress can happen to anyone at any time. People always mistake stress as only negative things, but there are both good and bad stress. First of all, what is stress or the definition of it? Stress is “Any event or environmental stimulus that we respond to because we perceive it as challenging or threatening” (Pastorino 504). In simpler terms, any event that a person encounters that could be difficult or threatening can give an individual stress. All of our reactions to it differ to every type of stressor

acceleration due to gravity calculated this way works well for objects near the Earth’s surface. How would you have to change the above equation if the object was 100,000 meters above the ground? (Note: this question refers to Newton’s equation for the force of gravity between two objects. How would that change if the radius of the earth or distance were increased by 100,000 meters. To help you answer this question, please review your textbook, chapter 3, Newton’s law of Gravitation section.) F= (6

technological design, and an ability to identify factors that affect motion and forces. Background Information: Bottle rockets are excellent devices for investigating "Newton's Three Laws of Motion": 1st Law - A rocket will remain on the launch pad until an unbalanced force is exerted, propelling the rocket upward. 2nd Law - The amount of force depends upon how much air is pumped inside the rocket. You can increase the force further by adding a small amount of water, which increases the mass expelled

Inmates have a variety of ways they deal with stress. Music, recreational activities, exercising and socializing. Life is full of expectations, commitments, deadlines, frustrations and demands. People are faced with stress every day that it has become a way of life. Stress is a response to evens that make you feel threatened or upset your balance in some ways. According to Gilabert (2007:10) stress is defined as an emotional reaction occurring in the presence of certain stimuli that usually trigger

Vernier Dual-Range Force Sensor Vernier LoggerPro software Procedure For this activity your team of four will construct simple machines using VEX components. After you have constructed the simple machines, you will gather data to calculate mechanical advantage. It is important to be as accurate as possible in your measurements and documentation. Terms to know to complete this activity: The Effort (FE) is the force that you apply to the system. The Resistance (FR) is the force or load that
