Goals:

This course is intended to cover theory and techniques of kinematics and dynamic analysis of
mechanisms. The course emphasises the practical design considerations of mechanisms and
machines.

Attendance

At
tendance will be checked at the beginning of each lecture. Late coming is strictly not
allowed as this disturbs students and instructor. Excuses for absence should be approved
by the Deanship of student affairs and submitted to the instructor within one week
following the last day of absence. University regulations will be followed for students
exceeding the maximum number of unexcused absences. In addition, 0.5% will be
deducted for each unexcused absence.


Homeworks

All homework problems assigned during a given week are due in class on the following
Monday unless otherwise stated. LATE home works will not be accepted.

Quizzes

Five quizzes will be scheduled during the semester
.
No make-up quizzes will be
conducted.
