Course description:

Students learn the principles of statics and their application to engineering problems. Topics include concentrated and distributed force systems and equilibrium conditions covering structures, machines, friction and methods of virtual work.

Objectives: Students will be able to

1. Solve basic problems in structural mechanics.
2. Analyze trusses to solve for equilibrium forces.
3. Sum distributed forces into an equivalent concentrated force.
4. Find centroids and moments of inertia of composite and three-
   dimensional bodies.
5. Compute three-dimensional forces and torques.
6. Use the method of virtual work as an alternative to solving statics
   problems.

Course Grading

You will be expected to complete fifteen regular assignments, 6 quizzes and a final exam.

The  total weights of different course activities:

15 Assignments (normalized to 6.6 pts each)                 33.3 %    
6 Tests (normalized to 20 pts each)                            33.3 %   (6 given, lowest dropped)                  
Final Exam (100 pts)                                                     33.3 %

            A - 90%
            B - 80%
            C - 70%
            D - 60%

All assignments are due on Wednesday, start of class each week. Late assignments will be marked off by 30%.

Homework

 50% of your grade is for completeness (all problems attempted), and 50% for correctness. Assignments shall be completed on separate paper, preferrably grid paper. In addition, points will be awarded or taken away as your work reflects or ignores the clear principles demonstrated in the example, including:

a) brief problem statement
b) neatly drawn picture
c) formulas used
d) math solution
e) underlined asnwers

These qualities are demonstrated in the following  Homework Example

Exams and Tests

Tests will cover just 2 homework assignments and therefore there is a limited number of possibilities in solving a given problem. Ultimately, the goal is to be able to look at a  problem covering any of the material covered and decide a  proper course of action in solving it. The final exam is therefore of a different nature than the tests.

 

Whereas tests are closed book, allow 1 sheet (2 sided) of notes, and focus on 1 or 2 chapters of the text,  the Final Exam is open book, covers the entire class, and provides an opportunity to assimilate and integrate the new and sometimes challenging concepts we discover each week, therefore,

 

EVERYONE MUST TAKE THE FINAL!

 

UNEXCUSED TEST ABSENCES

 

You must present medical evidence for failure to appear for a test. Otherwise you get zero for that test or lab. A total of seven tests will be offered but only your best six test scores will affect your grade. This allows you to miss one test without suffering a penalty.

 

CHEATING

 

Occasionally I have caught students cheating. The standard policy is to give a grade of F for both participants and if deemed necessary make a visit to the Dean of Students with the cheaters. We have had very serious cases in which the students were dropped from the course and suspended from taking courses at MPC. This goes on your record and of course is not viewed favorably by other schools and employers who want and need to trust you.

 

DROPPING THE CLASS

 If you wish to drop the class go to the registration office and officially drop BEFORE the last drop date,  November 18. Do not depend on me to drop you If you do not do an official drop then you will get a grade of F for the course. I am not allowed to give you a W after the last drop date.
