ABE 4171C
Power and Machine Design in Agriculture and Biological Engineering

Semester Taught - Fall of odd numbered years

Catalog Description

Credits: 3

Design and specification of power and machine elements applied to agricultural, biological and land and water resources or food engineering; fundamentals of power units, design of machine elements and power transmission.


EGM 3520 and EML 3007

Course Objectives

  • Gain ability to design, test, and analyze power and machinery systems, which can be applied to a broad range of engineering applications including, but not limited to, field production, food processing, irrigation systems, and biological systems.
  • Learn theoretical concepts associated with power and machinery design. Theory will be reinforced during laboratory exercises.
  • Learn how to evaluate mechanically oriented design problems, formulate a solution, design and specify components, develop a formal report and present concepts to class. Students will develop team skills and communicate ideas in written and oral format. Project will reinforce need for ethical design practices.

Attendance and Expectations

  • a) There will be approximately one homework assignment per week. No late homework will be accepted. Your lowest homework score will be dropped to accommodate an unexpected situation. You may discuss homework, but you may not copy verbatim homework from another student. Cheating on homework will affect all parties involved.
  • b) There will be a daily quiz (typically one per week) that will cover content from that days lecture and will account for 5% of class grade.
  • c) The design project will more fully expose the students to the material being covered in the class. The project will require the student teams to write up a project report describing the work they have done and documenting all design calculations.
  • d) Two mid-term and a final exam will be given.
  • e) There will be a term paper required that will cover contemporary issues in engineering design of automated machinery systems. The paper will focus on the multi-disciplinary nature of automated machines, their evolution, as well as the impact that automation is having on the economy and global society.


A C- will not be a qualifying grade for critical tracking courses.  In order to graduate, students must have an overall GPA and an upper-division GPA of 2.0 or better (C or better).  Note: a C- average is equivalent to a GPA of 1.67, and therefore, it does not satisfy this graduation requirement.  For more information on grades and grading policies, please visit:

Academic Honesty

As a student at the University of Florida, you have committed yourself to uphold the Honor Code, which includes the following pledge: “We, the members of the University of Florida community, pledge to hold ourselves and our peers to the highest standards of honesty and integrity.”  You are expected to exhibit behavior consistent with this commitment to the UF academic community, and on all work submitted for credit at the University of Florida, the following pledge is either required or implied: "On my honor, I have neither given nor received unauthorized aid in doing this assignment." 
It is assumed that you will complete all work independently in each course unless the instructor provides explicit permission for you to collaborate on course tasks (e.g. assignments, papers, quizzes, exams). Furthermore, as part of your obligation to uphold the Honor Code, you should report any condition that facilitates academic misconduct to appropriate personnel. It is your individual responsibility to know and comply with all university policies and procedures regarding academic integrity and the Student Honor Code.  Violations of the Honor Code at the University of Florida will not be tolerated. Violations will be reported to the Dean of Students Office for consideration of disciplinary action. For more information regarding the Student Honor Code, please see:  

Accommodation for Students with Disabilities

The Disability Resource Center coordinates the needed accommodations of students with disabilities. This includes registering disabilities, recommending academic accommodations within the classroom, accessing special adaptive computer equipment, providing interpretation services and mediating faculty-student disability related issues.

Software Use

All faculty, staff and student of the University are required and expected to obey the laws and legal agreements governing software use. Failure to do so can lead to monetary damages and/or criminal penalties for the individual violator. Because such violations are also against University policies and rules, disciplinary action will be taken as appropriate. We, the members of the University of Florida community, pledge to uphold ourselves and our peers to the highest standards of honesty and integrity.

Campus Helping Resources

Students experiencing crises or personal problems that interfere with their general well-being are encouraged to utilize the university’s counseling resources. The Counseling & Wellness Center provides confidential counseling services at no cost for currently enrolled students. Resources are available on campus for students having personal problems or lacking clear career or academic goals, which interfere with their academic performance.
