Walter D. Thomas, Ph. D. Lecturer Kitson 210F walter_thomas@uml.edu DEPARTMENT OF MECHANICAL ENGINEERING University of Massachusetts Lowell 22.211-­‐203 Fall 2015 Course Syllabus Instructor: Dr. W. D. Thomas Office: Kitson 210F Office Hours: Wed noon – 2 pm, Thurs 3 -­‐ 5 pm Email: walter_thomas@uml.edu Phone: 978-­‐934-­‐5276 (office) Class times, room: Tuesday & Thursday 11:00 – 12:15 pm, Kitson 301 Textbook: Engineering Mechanics: Statics by R.C. Hibbeler (11th, 12th or 13th ed.). Electronic (eBook) editions of the text are allowed. Catalog Description: The application of Newton's Laws to engineering problems in statics. The free-­‐body diagram method is emphasized. Topics include vector algebra, forces, moments of force, couples, static equilibrium of rigid bodies, trusses, frames, machines, friction, properties of areas and composite bodies, and moments of inertia. Prerequisites: 92.132 Calculus II and 95.141 Physics I Course Objectives: To develop the ability to set up and solve engineering science problems in statics. The use of vectors and free body diagrams is stressed throughout. Tests: There will be three tests given during the semester, plus a final exam, as noted in the schedule below. The coverage of material will generally span two or more chapters and will require an ability to synthesize ideas from multiple chapters. All tests are administered in a larger lecture hall so that students will have room to spread out. Test 1 Chapters 2 -­‐ 3 Monday, Sep 21st, 6 -­‐ 8 pm Test 2 Chapter 4 Thursday, Oct 8th, in-­‐class Test 3 Chapters 5 -­‐ 6 Monday, Nov 16th, 6 – 8 pm Final Exam Chapters 7 – 10 TBD No makeup tests will be given. If you miss a test for ANY reason, you will receive a grade of zero for the test. There are two exceptions to this policy: 1. You are participating in a university-­‐sanctioned activity during the time in which the test is given (for example, you have another test at the same time or you participate in a NCAA sport and have a game during the test time). 2. You have a legitimate, regularly-­‐scheduled job during the time the test is given. In either case, you must make arrangements, in advance, with the course instructor to take the test at a different time on the same day that it is given to the class. All tests and the final will be closed book, closed notes. Grade Composition: In-­‐class Quizzes 15% 3 Tests 60% Final Exam 25% Total: 100% Notes: • You are required to take all three in-­‐semester tests. The test with your lowest grade counts for only 10% of your course grade, and the other two count for 25% each. • Quizzes will consist of problems identical to or very similar to homework problems. Homework: Homework will be assigned on a regular basis, usually once per week. However, homework will not be collected nor graded. It is assigned so that students have the opportunity to practice solving problems similar to ones they will see on both quizzes and tests. Students are encouraged to work together in small groups to discuss the approach and better understand the homework. The following grading scheme will be used: 90 ≤ semester average < 100 A 80 ≤ semester average < 90 B 70 ≤ semester average < 80 C 60 ≤ semester average < 70 D Semester average < 60 F Grades will be dependent on your work and performance. Grading will NOT be conducted on a curve. When assigning final letter grades, +’s and -­‐‘s will be used. ***Note: Mech Engineering Department policy requires a grade of C-­‐ or higher in Statics in order for a student to take Dynamics and/or Strength of Materials. Therefore, if you receive a 2 D+ or lower in Statics, will not be allowed to take those two courses until you have repeated Statics and earned a higher grade.*** Attendance: The University of Massachusetts Lowell policy on class attendance is in effect for this course. Note: if you are on the cusp of a higher final grade (e.g., you have an 79.7 average), then consistently attending each class will have a positive influence on the grade you receive. Classroom Demeanor: The expectation for students to participate as engineering professionals is implicit. Turn you cellphones’ ringers to “silent” or simply turn them off in class. Email Policy: When required, I will send class information to students via email using the Intercampus Student Information System (ISIS) system. ISIS sends emails to your UML student email address. Every student who registers for courses at the University of Massachusetts – Lowell receives a UML student email address. Students are responsible for checking this email account for messages from the Instructor for this course. Wiki Page: I will post homework assignments using a class “wiki” space, as well as solutions to homework and other class material as necessary. The URL for our wiki is http://22-211-203fa15.wiki.uml.edu . I will “invite” all students to join this wiki at the beginning of the semester. Academic Support: Please contact me privately if you need accommodations because of a disability. The University’s Policy for Students with Disabilities will be followed for this course (http://www.uml.edu/student-­‐services/disability/policy.html). Honors and Ethics: Engineers have a trust placed on them by society to ensure that the public safety is held paramount. People constantly depend on engineers to provide safe bridges, buildings, drinking water, etc. This trust must not be violated. For this reason, no form of academic dishonesty will be tolerated in this class. Students are encouraged to work together on homework assignments and class projects (if assigned). However, any evidence of direct copying of a homework assignment will result in a zero grade for that assignment for all students involved. Any evidence of academic dishonesty during a test or the final exam will also result in a zero grade for that assignment for all students involved. Refer to the University of Massachusetts – Lowell’s Academic Integrity Policy for additional details. (http://www.uml.edu/catalog/undergraduate/policies/academic_dishonesty.htm). During tests and the final exam, only calculators that cannot communicate with other electronic devices are allowed. Students are encouraged to use calculators approved for the Fundamentals of Engineering (FE) exam to prepare themselves for the FE Exam. Information on FE Exam can be found at 3 http://www.ncees.org/Exams/Exam-­‐day_policies/Calculator_policy.php. However, the use of the approved FE calculators is not required. All other electronic devices, such as mobile phones, music players, computers, tablets, etc. are not allowed during the tests and the final exam. 4 Course Objectives: ABET No. Course Objectives 1 2 a-­‐k Utilize the English and SI systems of units in solving engineering problems.
