Required Text: Machine Design: An Integrated Approach. Norton. Prentice-Hall, 2006. Fourth/Fifth Edition. Course Description: The purpose of this course is to teach you the basic science, engineering, and analytical tools required to build useful machines. Insofar as mechanical engineering is the design and construction of machines and mechanical devices, this course is truly the core of mechanical engineering. The first part of the course will review and build upon material from Statics, Mechanics of Solids and Material Science to determine how materials bend and fail and to ensure that parts of our machines do not deform excessively or fail prematurely. The second part of the course surveys common machine elements and introduces a process for effectively incorporating them into mechanical designs. A hands-on lab session and semester design project will reinforce the lectures and homeworks and allow you to ‘learn-by-doing.’ "Lecture" Sessions: There are two 75 minute "lecture" sessions each week on Tuesdays and Thursdays. The word "lecture" is in quotes because we do not intend for these sessions to be dominated by what you normally think of as lecturing. The "lecture" sessions will be used to introduce new material, to do interactive exercises, to practice the new material with group exercises, and to provide feedback on homework assignments and exams. We expect you to be present at these sessions A traditional point system will be used to grade the exams. Please include your name and ME ID number on each homework. A traditional point system will be used to grade the quiz. A review session will be held in class before each exam. Clicker questions will be used to assess attendance throughout the semester. in-class exercises. After this time period. The quiz will test your understanding of the machining. the homework will not be accepted. A review will be held during class before the quiz. All problem sets are to be completed using engineering paper in order to receive full credit. and dimensioning of drawings. In general. This quiz is worth 5% of the semester grade. "Lab" Sessions: You will attend one 2 hour "lab" session each week. See Homework Late Policy below. Homework Homeworks are to be completed by each individual student. Individual Work (60%): 40% Exams 5% Quiz 9% Homework 6% Peer Review Scores and In-class Participation Teamwork (40%): 10% In-class Workshops 30% Design Project Exams Two in-class exams will take place during the semester. These two exams will cover the material during the Material Fundamentals and Machine Components blocks. Late homework will be accepted for half credit (check-minus. Grading: The course grade will be based on a combination of individual scores on tests and homeworks. project milestones prepared by you and your project partners. Each Page 2 . and project group meetings.and to participate thoughtfully. See the MCEN 3025: Common Syllabus Material for exact format procedures. Please note: this course is based on an absolute grading scale (no curving). and your final team project. 5/10). this time will be dedicated for you to meet your teammates to work on the group design project. You will be able to pick-up homework at any time in the MCEN 3025 filing box on the first floor of the Department of Mechanical Engineering. Quiz An in-class quiz will take place after the manufacturing review block. Homeworks turned after the “start” of class are considered late. The word "lab" is in quotes because the session is a mix of training seminars. fabrication. Homework will be graded using the check system (see below). Each exam is worth 20% of the semester grade. Late homework may be submitted anytime after the “start” of class on the due date and the following class period. FEA. obviously. In-class workshops are graded using the check system (see below). . Design project grades will use both the check system and traditional point system.mechanical engineering student has been assigned a folder in the filing box using their ME ID number – graded homework will be placed in these files. Periodically. it is clearly legible) and the answers match the answer key. . a peer evaluation will be required of all students in which they describe the effort made by each member of the design team. Check System In class workshops and homework assignments will be graded on the check system: . you will receive a check (8/10). you will receive a check-minus (5/10). Turning in a workshop that one lab partner did not participate in is an Honor Code violation for both the student who did not participate and the four students who did. In-class participation will be measured using clicker questions. you will receive a check-minus (5/10). . Each team member is expected to contribute $30 toward supplies and equipment for the project. Design Project There will be one semester-long design project in this course.If you made some effort.And. but the answer is not. You will need to purchase additional materials in order to complete your projects.If the grader can follow the documented work (i. but were way off in approach. Peer Review Scores and In-class Participation The peer review score will be calculated using feedback provided by your design team members. In-class Workshops There will be a variety of in-class workshops throughout the semester. You will choose your own teams— all teams will include 5 students. grading rubrics will be provided before each milestone. If you were not in class to start the workshop with your group.If the grader can follow the documented work and your approach is correct. The workshops will be held during “lecture” on Tuesdays and Thursdays. Attendance at most of the lecture sessions is required to earn the in-class participation points. A detailed description of the design project will be handed out as a separate document. you should not participate in the out-of-class meeting.e. but allowed the fifth student to take credit for their work.If we can not follow your work. Page 3 . no effort will earn you a 0/10. you will receive a check-plus (10/10). There may be times that your group will need to meet for 15 or 20 minutes outside of class to complete the workshop. If you are not present you receive no credit. You must come to class and participate in order to receive credit for the workshops. Workshops will be due at beginning of the next class.
