BME 201 BIOMECHANICS 1 SYLLABUS

of 5 12/8/2017

Instructor: Professor Currey; Steinmetz 215; [email protected]; 388-8783 Lectures: Mondays, Wednesdays, & Fridays 11:45 AM to 12:55 PM in NWSE 114+ Laboratories: Tuesdays 9 to 11: 55 AM and 1:55 to 4:45 PM BUT 106 with Prof. Khetan Office Hours: Officially, Mondays 2:30 to 3:30 PM & Thursdays 10-11 AM or by appointment Required Text: Hibbeler RC. Statics and Mechanics of Materials. 5th e. Pearson, 2017. Course Website: http://orzo.union.edu/~curreyj/BNG-201.html Register Description: “A basic biomechanics course concerned with two- and three-dimensional force systems, equilibrium and distributed forces. These topics will be studied in the context of the musculoskeletal system. This course also introduces strength and elastic deflection of biological tissues due to loads applied axially, in bending, and in shear. Shear and bending moment diagrams, friction, and area moments of inertia will be introduced. Prerequisite(s): MTH 110 or equivalent and PHY 120.” Homework: Homework will be assigned each class. It will be collected at the start of following class (i.e Monday’s homework will be due Wednesday, Wednesday’s homework due Friday, and Friday’s due Monday). Homework must be completed on engineering paper using the problem format presented in this syllabus. Homework will be graded based on completeness, correctness, and neatness (i.e. following the problem format). Collaboration is encouraged on homework since this is one of the best ways to learn, however, each student must turn in their own homework assignment with their own work noting whom they collaborated with. Exams: There will be three (3) exams given during the term. The dates for the exams can be found on the syllabus. Exams 1 and 2 will be administered during the class period. Exam 3 will be administered during the period scheduled by the College in finals week. The exams will be closed everything, but necessary formulas will be provided as the exams are meant to measure comprehension not memorization. Laboratories: Lab attendance is mandatory. There will be five lab sessions devoted to Statistics. The remaining lab sessions will be used to work on three lab exercises. A brief lab write up must be completed for each exercise. We will talk in detail during the labs about how to write up the lab. Grades: Course grades will be determined using these weights: 15% for homework, 60% for exams, and 25% for the laboratories (lab attendance, reports, and statistics homework); and using this scale: ≥93=A, 90-92=A-, 87-89=B+, 83-86=B, 80-82=B-, 77-79=C+, 73-76=C, 70-72=C-, 60-69=D, and ≤59=F. All grading must be contested prior to the beginning of the lecture period following the period at which the original assignment was returned. Contestations must be accompanied by a written explanation of how your solution was incorrectly penalized. Attendance, Punctuality, and Class Conduct: Students are expect turn off their cell phones upon entering class. Students are expected to show respect for the professor and the rest of the class by refraining from using a computer or texting on their phone. Each student will be responsible for knowledge of all scheduling changes and announcements made in class. Without exception no prior, late, or makeup quiz, laboratory, exam, final exam or any other assignment will be administered, accepted, or allowed without a College approved excuse. Please use a "full credit designation" instead of an unapproved excuse. Laboratory attendance is mandatory, and an absence will result in no credit for the associated assignments. Honor Code: “By joining the Union College community, every student agrees to understand and abide by the Honor Code and Affirmation that is hereby set forth. It is the responsibility of the student to ensure that submitted work is his or her own and does not involve any form of academic misconduct. Students need to exercise common sense in making decisions regarding their academic conduct in and outside of the classroom. All students are expected and encouraged to ask their course instructor for any clarification regarding, but not limited to, collaboration, citations, and plagiarism.” Further details about the honor code can be found at: http://muse.union.edu/honorcode/

Students with Disabilities: From the Disabled Student Services website: “The Director of Student Support Services provides assistance to students with disabilities ... Students with disabilities who require accommodations must make a formal request by submitting documentation of the disability and accommodations requested.” Please present the approved request to the Instructor within the first two weeks of the term, in total confidence and at your discretion. Homework Format and Grading: Engineering REQUIRES careful precision and attention to detail. Your work is a presentation. Solutions to each and every submitted homework problem must be completed on engineering paper in the format provided. This method should help keep you organized, focused, and thinking like an engineer (it will also mean you don't have to carry your book everywhere to do your homework). Consider these guidelines a checklist for helping you complete your homework, as they will also likely serve you for years to come in this program and beyond. Note that homework solutions will be posted online after the homework has been collected. Each problem will be graded out of 10 points. Two homework problems will be assigned each class and will be collected the following class (i.e. Monday’s problems will be due Wednesday). Homework Requirements & Grading:

• (+1 pts) Tools o Use green engineering paper o Write in pencil o Be neat

• (+ 5 pts as follows) Write-up o (+1 pts) Clearly state problem and provide given information.

§ DO write out the full problem statement o (+2 pts) Draw FBDs/Motion Diagrams as appropriate

§ Given sketch from book is NOT sufficient § Draw & label known/unknown forces (-1 pt) § Failure to define and label coordinate axes or inconsistent (-1 pt)

o (+2 pts) Solution Method - All steps necessary to solve § Write out governing equations before plugging in to solve § Show enough steps so that someone can follow solution § Failure to provide governing equation then substituted version (-1 pt)

• (+ 4 pts) Final answers o Failure to include correct units (-1 pt) o Failure to use correct vector or scalar notation (-1 pt) o Failure to double underline or box each final answer (-0.5 pt) o Failure to round correctly (3 sig figs, 4 if first digit is a 1) (-0.5 to -1 pt)

NOTE: FBD DEFINES the meaning of a negative sign in your answers so you MUST include FBD and assumed directions of forces or motion. If not included your answer cannot be considered correct, nor does it communicate the results you've obtained. Grading appearance on page: Point totals will appear on your page as follows for the following categories along with any notes, deduction info, suggestions, etc. Each of the following will be out of 2 pts maximum per category: +XX for "Tools" +XX for "Problem Statement" +XX for "FBDs and Sketches" +XX for "Method" +XX for "Answers" --------------------- XXX = Final Score --------------------- Corrections: If you received at least a 5 on a homework problem, then you can earn up to half the remaining points back by correcting your work (i.e. go from a 5 to a 7.5). I also expect a good faith effort for your initial solution. If your initial effort seems to lack a clear attempt at solving the problem (no FBD, poor method), I may not allow any

points for corrections. To earn these points you must find the mistake(s) in your existing work, and correct your work providing a fully corrected solution. You will only earn points back if your final solution is entirely correct. The corrected problem(s) must be submitted at the start of the class period after which they are returned. You are allowed and encouraged to use my solutions posted online to aide in your corrections.
