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 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.

Do not wait until the day before a major exam for help, unless the tutor has office hours on that day. 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.

Textbook: The textbook is excellent  one of the best:
Looking for a used textbook? ORDER EARLY! Here is where a text I bought has been. Around the world in 30 days.
The ISBN Number is 0136077900 or 9780136077909. IF YOU ARE TAKING STATICS ONLY.
If you intend to take Statics and Dynamics in the CE Department, you might consider the combined Statics & Dynamics version of the text which will save you about $100 over buying the texts separately. This text ISBN Number is 0138149291 or 9780138149291. However, be sure to see if the dynamics class still uses the Hibbeler text. It may change in the future.
Catalog Description:
Application of the fundamental principles of Newtonian mechanics to the statics of particles and the equilibrium of trusses, frames, beams and other rigid bodies. Forces; moments; trusses; beams; free body diagrams; friction; equilibrium; first and second moments of lines, areas, and volumes; centers of pressure, mass, and gravity; and moments of inertia. Vector algebra and calculus are used. Prerequisites: Admission to a major sequence in Civil Engineering; MATH 251 or 253, or registration therein; PHYS 218.

28  Review for final exam  Fully understand what we covered today and be prepared to work similar
problems on the Final Exam. 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 Monday, Dec 12th, 2011 from 1:00 p.m. to 3:00 p.m. in room 110 CHECK THIS DATE AND TIME FOR ACCURACY HERE: 
The
final
exam will be closed book. 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. You are permitted to bring an 81/2"x11" sheet of formulas, both sides, no example problems. You should also 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.
