This course is intended to provide the techniques necessary to study the motion of machines.
A focus is
placed on the application of kinematic theories to practical mechanisms.
Mechanism synthesis is introduced
and applied to simple linkages.
The subject of the course is essential in the machine design process as such
analyses should
be performed on design concepts to optimize the motion of a machine arrangement..
Completion of ENGR 2043 with a minimum grade of C and MATH 3103 or concurrent enrollment in MATH 3103. Junior or senior standing.
Machines and Mechanisms, Applied Kinematic Analusis 4e by David H. Myszka (Pearson)"REQUIRED"
•Devise kinematic diagrams of mechanisms.
• Describe mechanism synthesis and design a linkage system to achieve a desired displacement.
• Determine the displacement, velocity and acceleration of any point on a mechanism, and construct
motion diagrams.
• Create computer routines to determine optimal design and kinematic properties of simple mechanisms.
• Determine the motion for a cam follower.
• Construct disk and cylindrical cam pro les.
• Determine kinematic and common geometric features of gear and planetary gear trains.
• Identify geometric and kinematic relations pertaining to belt and chain drives.
• Identify the operation and kinematic relationships of screw mechanisms.
• Weekly homework
problem assignment will be made. These homework
assignments will be collected
at the start of the period on their due date. Late
assignments will be graded as follows:
– 50 % reduction in grade if received prior to the next
class (after due date).
– 100 % reduction in grade if received prior to the second
class (after due date).
• Credit is given for submission of completed homework
problems. Homework should show evidence of
work, homework problems with only an answer will not be
accepted. Computer generated exercises
may be assigned during the semester.
• All problems and
homework must be professionally presented, stapled and
fastened securely. Problems
should be worked on engineering paper using one side only
and using pencil. Figures must be
presented drawn with a straight edge. Calculations and
Figures will be labeled and/or captioned to
allow the reader to go through the calculations without
difficulty. Printing and computer generated
calculations must meet graphics standards.
Assessments
in
this class are designed so that you may demonstrate your
competence in the subject:
Unit tests cover the material discussed in the class notes
and will normally be completed during class
meeting hours on the dates scheduled. Makeup exams will
not be given for any reason. Student who miss
one of the scheduled exams should contact their instructor
as soon as possible. No reference materials will
be allowed during assessments.
A
final
exam will be given on the scheduled date of this course on
the scheduled date of this course. Student
who miss the final exam should contact their
instructor as soon as possible and no later than the
last day of finals week to schedule a final exam. final
exam will not be rescheduled, and a grade
of ”I” will not be given as a result of the missed
exam.
The grade you
receive will depend entirely on the quality of your own
work. You are not in competition with other
students:
how well you do is determined objectively rather than
comparatively. Grades are assigned based on the
competence you demonstrate during assessments
(exams), project, homework and quizzes.
Criteria:
Your final
course grade will be determined according to the following
schedule: Quizzes (10%), Project (10%),
Homework (10%), First exam (22%), Second exam (23%), Final
(25%)
A > 90 % >
B > 80 % > C > 70 % > D > 60 % > F
