with experimental data. Unidirectional Ply- Transverse modulus: In this the rules of mixtures are less reliable than those for longitudinal properties as they are based on assumptions of stress distribution. In this the poisson’s contraction is ignored and the stress is assumed to be the same.which leads to the result of: E2=EfEm/(VfEm+VmEf). But the above rules of mixture has poor experimental agreement so an alternative Halpin-Tsai model

Lim - 008142015 Steven Reid - 007777066 Thomas Leininger- 008403601 Marco Evangelista – 007774076 Objective: The objective of this experiment is to determine the shear stress, shear strain, and shear modulus of elasticity of solid cylindrical specimens of steel, brass, aluminum, and a polymer. Procedure: 1. Plug the cord for the machine into the outlet hanging from the ceiling. 2. Zero the drum angle using start

Post-traumatic stress disorder (PTSD) is defined as a “disorder resulting from the exposure to a traumatic event that threatens the self or others with death or serious injury” (Barnett & Conway, 2012). Individuals with PTSD will usually have symptoms in four areas: intrusion, numbing, avoidance, and arousal (Barnett & Conway, 2012). The individual may feel impulsivity, aggression, alcohol/drug use, and dissociations as a result of the disease. This paper will summarize how the movie, “Perks of Being

Posttraumatic Stress Disorder Abstract Posttraumatic stress disorder is a common and disabling disorder that develops as a consequence of traumatic events and is characterized by distressing re-experiencing portions of the trauma, avoidance of reminders, emotional numbing and hyper-arousal. In spite of the deleterious impact of PTSD within the U.S. military, our current understanding of the human pathophysiology governing the divergent paths associated with extreme stress response the

Anger management Anger management is a cognitive behavioural technique based on a model by Ray Novaco in which he describes anger as a strong emotion with physiological, behavioural and cognitive elements. Anger management teaches relaxation techniques to deal with the physiological response to anger. For example, increased heart rate, cognitive restructuring to retrain through patterns and time out or assertive training to deal with the behavioural element of anger There are 3 steps in anger

Introduction The MecE 360 Shaft Design Project consists of designing a gear shaft within specified limits and given angular velocity and power for a certain application of the group`s choosing. This preliminary report will cover the preliminary geometry of the shaft as well as the calculations and information used to obtain this geometry. The members Group 19 have designed a preliminary shaft to be operated at an input angular velocity of ω = 554 rpm and an input power of P = 20KW to be used for

induced forces. Stress is the lead to accurately describe and predict the elastic deformation of a body. Simple stress can be classified as normal stress, shear stress, and bearing stress. Normal stress develops when a force is applied perpendicular to the cross-sectional area of the material. If the force is going to pull the material, the stress is said to be tensile stress and compressive stress develops when the material is being compressed by two opposing forces. Shear stress is developed if

Stress at Work Have you ever had a job or position that left you feeling pressure, anxiety, discontent, or completely disconnected? You are not alone; nearly everyone who is employed has experienced those feelings at one time or another in their life. The world, in which we live, is fast paced and ever changing. Companies have grown increasingly demanding and as a result the workload has increased while the workforce has not. As less people are used in the work force the workload is ever increasing
