Course Description#

Fundamentals of dynamics using vector methods. Rectilinear and curvilinear motion, translation, rotation, plane motion; work, energy and power; impulse and momentum. We will work through five course modules:

Course Objectives#

Applied mechanics II is the study of objects in motion and their interactions. It is the foundational knowledge for solid mechanics, fluid mechanics, aerodynamic studies, control theory, systems and mechanics, etc. Students are expected to use two disciplines to solve problems:

  1. Apply kinematics to rigid body engineering problems, including:

    1. Vector algebra

    2. Vector calculus

    3. Geometry.

  2. Appy kinetics to rigid body engineering problems, including:

    1. The Newton-Euler equations: \(\mathbf{F} = m\mathbf{a}\) and \(M = \frac{d}{dt}h\)

    2. Conservation of energy: \(T_{1} + V_{1} + W_{1\rightarrow 2} = T_{2} + V_{2}\)

    3. Conservation of momentum: \(\mathbf{F}dt = d(m\mathbf{v})\) and \(\mathbf{M}dt = d\mathbf{h}\)

  3. Apply kinematics and kinetics to solve a variety of engineering problems and use these disciplines to extend this work to problems in solid and fluid mechanics.

  4. Analyze, interpret, and communicate results from dynamic analysis.

  5. Create engineering design under constraints.

Course Expectations#

Students are expected to quantitatively describe the motion of objects using calculus, Newton’s laws of motion, energy, and momentum. Students should be able to identify degrees of freedom and solve for the position, velocity, and acceleration of rigid body objects based upon applied forces.

This course will introduce analytical and numerical solutions to dynamic interactions of objects. We will use Newton’s laws of motion, calculus, and algebra to derive differential equations of motion. We will use Python to analyze and visualize dynamic problems.

In order to be successful in this course I expect:

  • You watch all media content provided

  • You do the assigned readings and provide discussion content

  • You go through derivations on your own

  • You turn in all assignments

Applications#

  • Automotive design: cam shafts, power requirements (both engine and brakes), windshield wipers, frame design, etc.

  • Aerospace design: turbine blades, power requirements, flight tracking, etc.

  • Biomechanics design: artificial knees/hips/…, sports physics, health/fitness tracking, etc.

  • Sports: ball-tracking, speedometers, helmet design, equipment design (baseball bat, lacrosse stick,…), etc.

  • …

Note on Due dates#

All the course due dates are included in HuskyCT Assignments should be submitted before 11:59pm on the due date.

Due dates are flexible to account for personal scheduling. You do not need an excuse, but you need to put a note in the assignment submission that states:

  1. When will you submit the assignment?

  2. What help do you need?

If you need help with the material, we can set up a meeting. If you just need more time, I’m happy to provide an extra day to get to an assignment done.

Note on Participation grade#

The participation grade is based upon your own self assessment of how you add to our learning community. You will fill out 2 forms:

  1. Halfway: What is your current assessment? Why do you feel that way? I will help connect you to others if you don’t feel engaged

  2. Final: What is your final assessment? How did you participate? Ths is your final Participation grade.

You can add to the class in a number of ways including, but not limited to:

  • adding questions or answers to GitHub Discussions discussions

  • attending lectures

  • participating in a study group or group chat

  • sharing notes from lectures or videos

Note on Homeworks#

All hand-written solutions need a legible scan. Android users should use Google Drive’s Scanning function:

Google Drive scanning support (support.google.com)

iOS users can use the following upload instructions:

Download Scannable from the app store. Scan the document, press “send”, press “share”, select “Google Drive”, select “Upload”.

Note on Quizzes#

There will be five quizzes, one for each module. The quizzes are composed of 2-4 questions based upon the readings and homeworks. The class before quizzes for modules 01-04, I will ask you to design questions that demonstrate your understanding of the material. I will build the quiz based upon our discussion.

You will scan and upload your work to HuskyCT along with a 10-30-second video explaining your solution.

Note on the Project Report#

I want you to build a dynamics project that interests you. Ideally, you can use this project in an engineering portfolio to demonstrate your grasp of Newtonian mechanics. My goal is to help you build this solution in a Jupyter notebook.

Due Dates and Late Policy#

All course due dates are identified in the course calendar. Deadlines are based on Eastern Time; if you are in a different time zone, please adjust your submittal times accordingly. The instructor reserves the right to change dates accordingly as the semester progresses. All changes will be communicated via the calendar or another appropriate notification.

Late Policy: If you need more time for an assignment or experience technical difficulties, reach out via GitHub Discussions or email. The instructor can make accommodations for work, family, and personal reasons. We ask that you be respectful of the instructors’ limited time and resources.

Feedback and Grades#

I will make every effort to provide feedback and grades within 7 days. To keep track of your performance in the course, refer to HuskyCT grades.

Weekly Time Commitment

You should expect to dedicate between 6 - 10 hours a week to this course. This expectation is based on the various course activities, assignments, and assessments and the University of Connecticut’s policy regarding credit hours. More information related to hours per week per credit can be accessed at the Online Student website.

This course requires lots of practice. You should set aside 1-2 hours per week to write out example problems from the textbook, try homework problems, and revise answers. This is the best way to learn and understand the material.

Student Authentication and Verification#

The University of Connecticut is required to verify the identity of students who participate in online courses and to establish that students who register in an online course are the same students who participate in and complete the course activities and assessments and receive academic credit. Verification and authentication of student identity in this course will include:

  1. Secure access to the learning management system using your unique UConn NetID and password.

  2. Students will submit videos to describe solutions to the 6 module quizzes.
