BioE 102 - Introduction to Biomechanics: Analysis and Design (4 Units)

Course Overview

Summary

  • (from course syllabus) BioE 102 “introduces, develops and applies scaling laws and the methods of continuum mechanics to biomechanical phenomena related to tissue or organ levels.”
  • Mostly lectures on derivations and examples for applications
  • Some guest lectures on more advanced topics towards the end of the semester
  • Weekly or biweekly problem sets focused on fundamentals during the first 2/3 of the course (7 in total)
  • Two midterms and one final each with one cheat sheet
  • One project with one video and one paper
  • Textbook: An Introduction to Biomechanics: Solids and Fluids, Analysis and Design (Jay Humphrey and Sherry O’Rourke), Springer 2015

Additional Comments and Tips

Prof. Mofrad is a really nice and fun professor who tries to know each individual student on a personal level and really cares about how he can improve the course as well as students’ learning experience. He also tried to give fair exams as he believes there should be no trick questions:

  • He usually gives the problems covered in the discussion to the GSI and they could be helpful for exams.
  • Pay attention to what he commented as good questions in the lectures.
  • Review the HWs and the midterms you took

The course experience might vary depending on the professors and the GSIs.
