A bar is supported by a ball-and-socket joint and two cables as shown below. a) Draw a clear and neat free body diagram (FBD) for the bar. This FBD must be a figure that is separately from the figure given below. b) Determine the reaction at support A (the ball-and-socket joint). Express the force in Cartesian vector form. c) Determine the magnitude of the tension in each cable.

English 1050 Introduction Assignment In place of doing a simple introductory/biography discussion in week one, you’ll be posting a brief mixed-genre essay in week two. For this first assignment, you’re required to use your mobile phone. You may be asking: “Why on earth am I using my mobile phone in a writing course?” Well, our writing skills and writing style are shaped by our actions and our surroundings; we make sense of our environment through writing. Similarly, most of us make sense of our environment through the use of our mobile phones; we look up things we don’t know, we take pictures of things we want to remember, we make lists, communicate with people, entertain ourselves with games and social media sites, etc. Think of this assignment as an answer to a simple question: “How does my mobile phone shape and define my life and the way I digest/interact with my surroundings?” During week one of the course, you need to capture images with your camera, screenshots of your phone, and a list of activities (such as, taking pictures, looking up things on the Web, playing games, using social media, reading). At the end of week one, gather all of your images and activities and spend some time writing a short essay (2-3 pages minimum) that outlines your mobile phone activities for the week. You should also embed the images that you took using your mobile phone into your essay. In your essay include the following: An introduction paragraph: You might start off your paper with a discussion of what you used your phone for during week one and how you kept a log of your activities. Perhaps you’ll also include a discussion of your overall view of mobile phone use in our culture based on your experience reading the short essays in week 1. Body Paragraphs: The way you shape these body paragraphs and what you put in them will be based on your activities during week one. You might consider things, such as how you think your mobile phone shapes you as a creative person, thinker, learner, or academic. Or you might consider how these activities helped you write this essay, or how you use your phone to help you write in general, for example, using the notes or voice memo features to record ideas for your school work. A conclusion paragraph: As you conclude your essay, you might consider reflecting on the idea of your mobile phone defining or representing you as a person. You might consider whether you feel like the activities recorded really show who you are and what you enjoy doing. Further, you might consider how you could use your mobile phone more often to help assist you in being a writer, thinker, academic on the go. Once you finalize your essay at the end of week one, please post it as an attachment to the week two discussion thread no later than Wednesday by 11:59 p.m. EST of week two. Then make sure that you reply to at least two of your classmates’ essays no later than Saturday by 11:59 p.m. EST of week two. Alternate Assignment: If you don’t own a mobile phone, or you don’t use if except to make phone calls, then write about why you’ve chosen to opt out of such a cultural phenomenon and how you think not being tied to your cell phone defines you. Also, consider what other technologies (mobile or other) define you, for example, television, video games, computer/Internet time, etc.

To: ME200 Students From: Dr. Kevin Schmaltz Date: August 31, 2015 Subject: Ethics Assignment 1 INTRODUCTION: Engineering Ethics, or Professional Ethics, is at the center of the engineering profession, involving a social contract between the engineer and general public. In exchange for the freedom to police our own members, formulate technical standards and receive financial support for engineering education, engineers are expected to protect the welfare of society in technical decisions and behave in an acceptable professional manner. ASSIGNMENT: Assume that you are a relatively low/medium level Ford engineer (definitely not “management”) involved in the early stages design of the Ford Explorer. You have become increasingly aware and concerned about safety issues with the Explorer design. You are being asked to move forward with the design and begin vehicle manufacture. You need to provide a reason for doing so, or not, on the basis of engineering professionalism (ethics): • Clearly state the facts of the case (you will need to investigate some additional details) • Create an Ethics Decision Matrix (from section 1.10 of the Exploring Engineering text), modify the left column to use NCEES Model Rules Professional statements (given with this assignment), and modify any of the top Decision Options across row with options that would be most applicable to the Ford Explorer case • Fill out the table with a yes/maybe/no in each box. • Then use your Decision Matrix to defend your position to move forward or not. You are looking to convince your “managers” to take your recommended course(s) of action. OUTCOME/DOCUMENTATION: Work individually to complete this assignment. This assignment does not require a cover memo, and is due on September ????. Submit to Blackboard, and also bring this assignment to class. Engineering Ethics Decision Matrix Decision Options  NSPE Cannons Go along with the decision Appeal to higher management Quit your job Write your state representative Call a newspaper reporter Hold paramount the safety, health and welfare of the public Perform only services in your area of competence Issue public statements only in an objective and truthful manner Act for each employer or client as faithful agents or trustees Avoid Deceptive acts Conduct yourself honorably The yes/no tally: Grade for ME200 Ford Explorer Ethics Case Attributes Absent Novice: some of the elements are present. Intermediate: most of the elements are present. Proficient: all elements are present. Organization/Coherence: Statement of ideas is grammatically correct, professionally formatted. Author’s intent is clear. Identify constituents: Clear indication of the parties impacted by the ethical dilemma. Describe purpose/dilemma: Ethical dilemma described, implications are conveyed. Develop resolution/solution: Methods for resolution are presented, comparisons made between solutions, and alternatives discussed. Student Name/Score: /20
