STATICS - CVEN 221 Section 502
The Art of Making Things Sit Still
Course Syllabus - Spring 2010 
TR 2:20 - 4:10 in CVEN Room 110

What's wrong with this picture? (Rube Goldberg was not statics savvy)

What really happens:  Weight of cannon ball on unbalanced lever rotates lever, dropping cannon ball on ground hog, killing it instantly.  Golfer unfortunately also killed when entire mechanism rotates clockwise, impacting right end on ground, dynamically transmitting reacting force to left end of mechanism, snapping golfer's neck.  Adding insult to injury, impact bends gun barrel such that tee projectile wounds local video reporter on scene.  Reporter taken to hospital, reports animal rights violation to ASPCA who call Animal Cops.  Video of crime goes viral on YouTube.  Riots break out.  Golfing banned.

The gentleman shown here made a D in my statics class last semester.

Please note that although your grade in CVEN 221 will be highly influenced by your ability to do everything covered in the class, you MUST be able to find forces in trusses by the methods of joints and sections, you MUST be able to calculate reactions on beams, you MUST be able to draw shear and moment diagrams, and you MUST be able to find the centroid and moment of inertia of plane composite sections, or you will not pass. These things are critical and your professors teaching later courses will flunk you and pillory me if you go into their class unable to perform to this minimum level of competency.

Help for this course is available from the people shown below, at the office hours listed only.

I try and keep my calendar up to date, and to add unexpected meetings as they arise. However, it will always be in your best interest to call before you come by, unless you are already in the area.

Half of my time is spent teaching CVEN 305, CVEN 221 and ENGR 485. During the remaining hours I am a departmental adviser and do multi-media teaching research and am unavailable for tutoring. Please plan on assistance either during my office hours, or see a teaching associate during their office hours.

Pick up any homework you missed at my office.
 

 

Final Exam covers everything in the course, with emphasis on the last material over which you have not yet been examined.

Held on Wednesday, May 12th, 2010 from 1:00 p.m. to 3:00 p.m. in room 110

CHECK THIS DATE AND TIME FOR ACCURACY:

University Final Exam Schedules

The final exam will be open textbook (Hibbeler). It will cover everything in the course with emphasis on the material covered since the last major exam. The distribution of material is planned to be approximately: 20% over Quiz A materials, 20% Quiz B, and 60% over the material covered since Quiz B.

(NEXT SEMESTER - Not Fall 2010 semester - You are also permitted to bring a copy of the Fundamentals of Engineering Reference Manual, Statics section only.  Click here for a copy.)

Please note that to pass this class you MUST be able to solve for reactions and draw shear and moment diagrams, find forces in truss members by method of joints and method of sections, determine the location of a centroid for a composite shape and the moment of inertia about that centroid. These are minimum competencies without which you MUST find a better prof and retake this class.
