Interactive Web Based Animation Software: An Efficient Way to
Increase the Engineering Student’s Fundamental Understanding of
Particle Kinematics and Kinetics

Developed animation software for Dynamics over the last 8 years
Used to increase the engineering student’s overall understanding of Dynamics.
Being considered as a supplement to the proposed text, Riley, Sturges, Stanley “Dynamics”, 3rd Edition (Wiley and Sons, Inc. New York) Estimated publication: 2011-2012.
OVERVIEW
![Page 3: Richard Stanley, Ph.D. Kettering University Mechanical Engineering Dept Flint, Michigan Interactive Web Based Animation Software: An Efficient Way to Increase.](https://reader035.fdocuments.in/reader035/viewer/2022081514/56649dbd5503460f94aaf70a/html5/thumbnails/3.jpg)
Advantages: Each animation is directly linked to a specific
problem in the text. There is no software to install; the software is
Adobe Flash based. There is absolutely no programming required of
the user. The software is extremely easy to use.
![Page 4: Richard Stanley, Ph.D. Kettering University Mechanical Engineering Dept Flint, Michigan Interactive Web Based Animation Software: An Efficient Way to Increase.](https://reader035.fdocuments.in/reader035/viewer/2022081514/56649dbd5503460f94aaf70a/html5/thumbnails/4.jpg)
Advantages: The software is flexible such that infinite
“what-if” scenarios can be created by the student or the professor.
The cost and time of development is relatively low
It is my experience that engineering students are visual learners. Visual learners benefit from this software.

Typical Problem Solving Methodology
Currently, most homework problems require the student to solve for a given variable at an instance in space and time
The student validates the answer in back of book
Professors usually follow the same routine.

Typical Problem Solving Methodology
The subject of particle Dynamics is the study of motion and not the calculation of a particle’s point at a particular instance in time.
This differentiation may be lost in the traditional classroom
Computer animations will help close this gap.

CONCLUSIONS Students believe that animations in engineering courses
will become more popular in the future. The animation software is easy to use; it requires
essentially no learning curve. The animation program is unique in that each animation
is linked to a homework or example problem; students unanimously support this way of utilizing the software.
Specific dynamics concepts, which are difficult to explain on the blackboard, are better understood when viewed in the animation program.
Students overwhelmingly recommend the software to professors who teach the subject of Dynamics.
