IPHY 4540 Biomechanics Prof. Alaa Ahmed Office Hours: Clare 101, Th best way to reach me Alternatively: Course web page on Desire2Learn Required readings on E-reserves

3
TAs Reese Beisser Office Hours: 1-2 pm Friday Adam Carahalios Office Hours: 9-10 Monday Erik Summerside Office Hours: 3-4 pm Wednesday Location: Clare 111

4
Reading NordinM and FrankelV, Basic biomechanics of the musculoskeletal system – First 1/3 of course EnokaRM, Neuromechanics of human movement, 4 th edition – Last 2/3 of course Download from e-reserves Link available on CULearn course page – password: biomechanics2013

5
Grading One grade for recitation + lab: Midterm #1 15% Midterm #2 15% Final Exam-Comprehensive 25% Quizzes10% i-Clicker/Class Participation 5% Lab Participation/Assignments 10% Projects 20%

6
Exams Midterm 1 : Feb 28 Midterm 2 : April 4 Final : May 8, 4:30-7:00 pm Note the above dates – they will not change Makeup exams will not be given Midterms cover material since last exam Final is COMPREHENSIVE

7
Problem sets and Quizzes Problem sets usually posted on Thursday – Not graded, key will be posted online – Can work together, but responsible for content Quiz almost every Thursday, based on problem set. Bring calculators to class on Thursdays. There WILL be a quiz on Thursday. Bring calculator, syllabus, and muscle handout. One quiz grade dropped

8
i-Clicker Questions Bring i-Clicker to class every day Can earn 1 point per day with a maximum of 20 clicker points To earn your daily point you must answer all but one of the questions for that day

9
Lab Projects Two lab projects (20% of total grade): – Journal Article Review project (5%) Individual – Experimental project (15%) can work individually or in pairs

10
Journal Article Review Project (5%) Select a scientific journal article from one of the following journals: Journal of Biomechanics Clinical Biomechanics Gait and Posture Write a critical review of the article, pretending you have been asked to review the manuscript by the editor of the journal and decided whether it is worthy of publication

11
Review Components Importance of the research question Originality of the work Delineation of strengths and weaknesses of – methodology – experimental – statistical approach – interpretation of results Writing Style and figure/table presentation Ethical Concerns

12
Experiment Project (15%) Experiment Project – Perform an experiment to answer a question – Create a computer/mathematical model to answer a question – Re-analyze data from literature

13
Requirements – Must deal with biomechanics (bio + movement) – Must research scientific articles – Must utilize what you learn in class – Must turn in a written report – Can work solo or in pairs – Work on it outside class – Get advice beforehand

14
Projects: Late Policy/Lab grading Due in class lose 10% for every day late Project days in lab are graded

15
Agenda Labs week after next (Jan 28 th ) Refresh anatomy, physics and TRIG There will be a Quiz on Thursday – Bring syllabus – Bring from Nordin book: Biomechanics of skeletal muscle chapter by Pitman (password= biomechanics2013) – Bring calculator – Refresh Trig (next slides)

16
Trig Review Right Triangles – Pythagorean Theorem: A 2 + B 2 = C 2 A,B =sides adjacent to right angle C=hypotenuse – SOHCAHTOA Sin=opposite/hypotenuse Cos=adjacent/hypotenuse Tan=opposite/adjacent

17
Trig Review Non-Right Triangles – Law of Sines: Sin(a)/A=sin(b)/B a, b are angles A, B are sides opposite a and b, respectively – Law of Cosines C 2 = A 2 + B 2 -2ABcos(c) – A,B,C are sides of a triangle – c is the angle opposite side C
