how much the bar or specimen is twisting and at what angle. This test can also be done in reverse order measuring the angle first, and recording the torque on the test material. The testing of a “torque-angle” graph can be somewhat similar to a “stress-strain” curve. There are a few different types of torsion tests * Torsion only: applying only a torque (what we had done) * Axial-torsion: Applying and axial, as in tension or compression, and a torsion force to the specimen * Failure:

ME Analysis Project #2 Christian Seymour Due Date: December 12, 2013 Abstract: The diameter for my shaft design was hand calculated to be 0.8756” for a factor of safety or 2. This factor of safety was expected to be the outcome in FEA SolidWorks and it was not. The reason for this is simply SolidWorks is not the best tool to use for complex designs and loads as ours was. It worked great for the simple beam deflection in the last project. Many times hand calculations are the long way

The Hyppolite Family “The purpose of this paper is to apply the Family Systems Stressor-Strengths Inventory (FS3I) to a family and present an analysis of the finding.” For the purpose of this paper the family will been known as the Hyppolite Family. The family discussed in this paper is considered a traditional nuclear family living in a single family home. Included is a Father Andrew Hyppolite (AH) age 38, a mother Katharine (KH), age 36, and four children Zoë , Timothy, Sarah, and Scott, whose

This makes them more stress and leads to some health problems. The leading cause of stress arises because of communication with Superior among married women employees of BPO companies, consequences of work life imbalance and interventions for work life balance. The study revealed that more than two third of the respondents reported work life imbalance primarily on account of work interference with personal life. Also concluded from this study, stress and burnout, ill-health and poor work
