MASSACHUSETTS INSTITUTE OF TECHNOLOGY Department of Aeronautics and Astronautics 16.010 / 16.020 Unified Engineering Systems Problems #1 and #2 Issued: Wednesday 3 September, 2003 Due: See page 5 ENGINEERING COMMUNICATIONS Objectives By the end of Systems Problem #2, you will be able to: Make and interpret engineering drawings of a simple object. Write a professional letter or memo to communicate technical information to a colleague. Discuss technical communication, its role in engineering, and potential communications pitfalls in the Conceive-Design-Implement-Operate (CDIO) process. Discussion Communication is essential to engineering. Without proper communication, your ideas and expertise cannot be conveyed to others efficiently, leading to errors that may increase costs, delays, and even lead to loss of life. Example Forms of Communication Graphics Written Notes Memoranda Emails Formal Letters Formal Reports Books Oral Informal Discussion Meetings Phone Calls Formal Oral Reports Schematics Engineering Drawings Data Plots Figures / Pictures / Photos In systems problems 1 and 2, we will focus on communicating a design concept for a glider (that you will design) using formal letters and engineering drawings. Rather than performing drawing as an isolated task, we will imbed it within the context of design and manufacture to more clearly highlight the importance of good communication in engineering. 1 of 8

Below is a simplified schematic of a design process involving two groups. One group designs and tests an object, the second group builds the object. For the engineering process to succeed, it is necessary that the two groups can communicate effectively. Group 1 obviously needs to transmit a clear, unambiguous drawing of the components of the object and the manufacturing process that should be used. Group 2 must communicate the outcome of the fabrication process (including any problems or failures along the way) so that Group 1 is able to properly report on the success of the project as well as to potentially redesign any faulty parts. FUNCTIONAL REQUIREMENTS AND CONSTRAINTS DESIGN COMMUNICATION ( e.g. DRAWING) FABRICATION EVALUATION REPORTING GROUP 2 GROUP 1 This is the basic model you will follow for this assignment. You will each get to play the role of designer and fabricator. This systems problem covers the following aspects of engineering: Conception/Design -- You will design a glider, make detailed drawings, write construction plans, and write a memo. This must be completed by 1PM Thursday September 11, 2003 . Implementation -- You will exchange drawings and fabrication instructions for the airplane with one of your classmates. You give your drawings to the person in class just below your name on the alphabetical list of Unified students. You get a set of drawings from the person in class just above your name on the alphabetical list. You must build the plane and write a memo to the designer evaluating the construction plans and drawings.
