mechanical and fluid systems. Solve prob
lems that involve
mechanical advantage in simple machines such as a lever, an
inclined plane, a wedge, gears, pulley systems, wheel and axle,
screw jack, and belt drive. Construct simple machines and analyze
their behavior. Differentiate between ideal me
and actual mechanical advantage. Calculate efficiency of a simple
machine based on mechanical advantage (actual/ideal) and based
on work (output/input).

understanding of the term torq
ue. Solve complex problems
involving torque. Balance different masses in a system by
establishing equal torques.

9.

angular velocity, and angular acceleration
. Apply these concepts to
the solu
tion of complex problems. Measure the angular velocity
and acceleration of a system.

10.

Give a definition and measure work and energy involving
rotational inertia. Define angular momentum. Contrast and
compare linear system to rotational systems. Solve in
ertial
problems.

for laboratory equipment. Assist other students and contribute to
group activities. Conform to all stated safety standards. Use
appropriate language in and out of the c
lassroom.

Class Attendance
Policy and College

As stated in the S
tudent
handbook
:
In compliance with Public Law 105
-
244, Kirkwood Community College makes a wide variety of general
institutional information available to students.

Productive Classroom
Learning
Environment:

Students will treat each other with respect and avoid using profane or
inflammatory speech that denigrates another’s race, ethnicity, gender,
or sexual orientation. Students who are disruptive will be
required
to
leave.

See student handbook

Plagiarism Policy:

Learning Envir
onment
Expectations:

The classroom and laboratory conditions will be conducive to teaching
and student learning. To promote and maintain that environment, all
pagers, cellular phones, and other autonomous means of communication
shall be deactivated during

instructional periods. RINGING OF CELL
PHONES DURING CLASS WILL RESULT IN POINTS DEDUCTED FROM
YOUR CLASS ROOM PARTICPATION AND PROFESSIONAL CONDUCT
GRADE. Participants are expected to come to class prepared to actively
participate in class.

American
s with
Disabilities Act:

Students with disabilities who need accommodations to achieve course
objectives should file an accommodation application with Learning
Services, Cedar Hall 2063 and provide a written plan of accommodation
to the accommodation being provided.

Student Evaluation:

Final Exam

A comprehensive final exam totaling 20% of your final

Unit Exams
-

Exams will be given after every 3 or 4 chapters totaling
40% of your
the next class period. In a rare situation where the exam can not be
made up in that time period, the student will need to make up the exam
during the final exam week and this exam will be different
than that
taken by the rest of the class. All exams will be cumulative.

Labs
-

Labs will be worth 30% of your final grade. Labs will be done in
groups of up to four people. You will lose a point per minute late if you
are late to a lab. THERE WILL BE
NO MAKE UP LABS!!!

Class Room Participation and Professional Conduct
-

10% of your
determined based on the
“Assessment_of_Contributions_of_Group_Members
“ sheet.

classroom participation and professional
conduct grade based on the following:

1. Arrival at class by 8 am (50 % of class participation grade)

2. Performing in class problems

3. Helping lab partner or other lab groups.

4. Helping other classmates.

Points will be deducted from the classroom participation and
professional conduct grade for the following:

1. Inappropriate language or jokes.

2. Ringing of cell phones in class.

3. Disrupting the class.

4. Leaving class early or not arriving back to c
lass by 9:00, after the 8:00
break.

5. Not cleaning up workspace at the end of the class.
