Strain Gauge Measurement

Safety: Your demonstrator acts as your safety warden. Follow all instructions given by your demonstrator. If the evacuation siren sounds leave your bags and follow the instructions of your demonstrator and proceed to the evacuation area. Place all weights on holder when not in use. Electrical: Ensure that all electrical apparatus has no signs of obvious damage. Report any damaged apparatus to your demonstrator.Do not attempt to fix any broken apparatus. Report any damage to your demonstrator. General: No food or drink is allowed in the laboratory.    Introduction: Strain Gauges are used in many systems to measure the deformation of structures and materials, from this forces, moments and stress can be calculated. In this experiment we will be looking at a system of seven strain gauges spread over the length of a steel cantilever beam and will be comparing the measured strain and stress with thetheoretical strain and stress. Theoretical Strain: e =Mc/IE      Where:e   is strainM is the momentc is the distance from centre of beam to point where strain is bean calculatedE is the youngs modulusI is the second moment of inertia  Theoretical Stress:  O=M/S  Where: S is the section modulus  Measured Stress: O=Ee   Where:  is the measured strain Apparatus:        Slotted masses Strain Gauge Gauge Reader Steel Beam ClampConnecting Wires Rule Digital Callipers Side Cutters    Procedure: 1.   Measure all required beam dimension using digital callipers and tape measure.2.   Connect all strain gauge wires to the gauge reader (information below). Check that all gauges are working by weighting the beam and checking for a change in strain.3.   Document initial readings for all strain gauges.4.   Apply 1kg of mass to the beam and document the new strain readings. Repeat for 2 and 3kgs.5.   Remove 1kg of mass and document the new readings. Repeat until all masses are removed. Gauge Reader As seen in Figure 1 the gauge reader consists of two banks and twelve position allowing up to 24 strain gauges to be positioned simultaneously. The reader has already been calibrated for 120ohm strain gauges with a gauge factor (k) of 2.09. Connecting a strain gauge 1.   Disconnect the power2.   Choose a free position in a bank and connect the white and black wires to the black pin and red wire to the red pin.  3.   Connect Power.4.   Move position and bank dials to the strain gauge position5.   Deform the material to ensure the strain gauge is working   Figure 1 Gauge Reader    Report: Provide an individual report. Although no minimum word count provided, I expect a high quality 3rd year engineers report. It must include (but not limited to). Summary: Contents: Introduction: Procedure:*Results: *Conclusion/Discussion: Appendices:   *emphasis should be put on these areas.

Management 2

Please answering following questions: 1. Please read the document on Ethical Decision Making. (See attachment below)a). Once you\’ve read article, please discuss what you thought was most interesting about this article.b). Identify a few specific practices on what you can do to become a more ethical person, employee and future manager 2. On page 35 in your textbook(See attachment below), there is a section on Ethics, \”Tracking Technology Monitors Worker Behavior,\” please read this section.  Please discuss your thoughts to the following questions:a). Should the use of tracking technology to monitor employee behavior be regulated by law, OR is it a practice that Employers have automatic rights to use at their discretion since an employee takes the job knowing he/she can/will be monitored?b). What message does the use of tracking technology communicate to the employees?c). Would you be comfortable taking a job where your actions would be tracked regularly by technology (not just what you do on the computer)? 3. In your textbook on page 42, please read the profile on \”Employers Differ on Hiring and Retention Strategies,\” profiling hiring preferences between Facebook and Zappos. a). Based on reading this segment, which organization would you prefer to join Facebook or Zappos, and Why did you make this choice. b). How could making a choice like this impact your career for the next decade (if it were a real choice)?. 4. In your textbook on page 60, Please read section \”Manager Behavior Key to Ethical Workplace,\” then review video Ethics and Management, then and answer the following a). Are there any surprises in the data shared about ethical behavior in the workplace, and if so, what surprised you?b). Do you believe as a future manager, you have an obligation to model ethical behavior to your employees, peers and your own managers – Why or Why not?c). Have you ever felt like you had to commit an unethical act at work to keep your job or get some type of reward or acknowledgment- Yes or No?  If you Yes, how do feel in retrospect about that experience? 5. On page 73 in your textbook, under the Reflect on the Self-Assessment, please follow the instructions on the Terminal Values assessment, complete parts 1, 2 and 3.  Once you completed the instructions for Terminal Values, then Answer only Questions A and B (NOT C or D unless you want to) in the interpretation section of the values assessment, on top of page 74.

Researching Community Partnerships

 Review the “Preview of Your Final Project” criteria sheet to help you focus your work this week. Before engaging in your research, make sure you have decided on the organization you would like to research in this class so you can apply the work you do this week to your final project.Your review should include all six articles. You should provide a 100-150 word paragraph for each source addressing the each of the four key ideas in your summary. Each article should also include a reference citation in APA format.:Remen, R. N. (1999 Jan.1). Helping, fixing or serving? Retrieved from:In the article, “Helping, Fixing, or Serving” (1999), Remen asserts that people see the world in three different ways broken, weak or whole.These viewpoints results in how a person connect to their world. Remen views serving as a way to moves beyond the expertise and incorporates both their serves strengthens as well as the strengths of others.Many times people seek to help or fix rather than service. Remen uses examples of an emergency physician sees delivering a baby as a service rather than fixing the problem. She shares how a nurse moved past professional protocols to serve her by removing her ileostomy. In these examples, she explains how experiences shorten the distance between the humans. Remen shows how serving rather than fixing or helping benefits all parties and impacts humanity.

Analyze the different ways you can adapt the environment to meet the needs of the children.

This unit analyzes the different ways you can adapt the environment to meet the needs of the children in your class. When designing your environment, it is important to keep in mind the skills that the children in your group are learning and have mastered. The way you arrange your classroom, and the materials you fill it with can have a big impact on the kinds of play and learning opportunities you provide to your students.For this Assignment, you will use the developmental milestone chart, unit readings, and four classroom models provided to analyze the physical design, developmentally appropriateness of materials, and need for adaptive materials for each age-level classroom model on the template located in Doc Sharing.For each classroom model, you analyze the physical design and materials and then:You will also include an overall two paragraph reflection describing how the developmental domains were incorporated, which theories influenced the design of the classrooms, and the selection of materials for each of the age levels. Be sure to incorporate citations and sources to support statements made.
