PPT-Engineering Mechanics Trusses

Truss 2 Definition of a Truss A truss is an assembly of straight members connected at joints No member is continuous through a joint Bolted or welded connections are assumed to be pinned together. At the center of mechanobiology is the cellular process of mechanotransduction or the way cells sense and respond to mechanical forces Many if not most of the tissues in the body contain mechanosensitive cells These include osteocytes in bone chondr INTERNATBuilding INTERNATBuildingWood trusses are engineered frames of lumber joined by galvanized steel connector plates, referred to commonly wood floor trusses are being used in residential and com 2 Common Types of Trusses gusset plate Manolis Veveakis, Thomas .

Folks, I just received a rather disturbing series of pictures of new construction currently going on in New Jersey.    Apparently these new-style wood trusses are commercially available and no longer use the metal "gusset plates" that we are all familiar with. This new breed of firefighter-killers is simply 2x4 Finger Jointed lumber (yeah, it's not even dimensional lumber) held together by little spots of glue where the webs meet the chords. Check out the attached pics... You also can see that these particular trusses are installed in townhouse-style occupied multiple dwellings. All that's holding them up is a 2x8 or TJI sill plate that's anchor bolted to the block sidewall.    I'm not an engineer, but it looks like it's actually the dead load and   live load from above that holds the house of cards together. My dad is a commercial sales manager at a large lumberyard. He is going to further investigate the manufacture and engineering of this product and I'll keep you advised of anything important to our operational safety.   If a standard gusset-plated truss will fail in less than five minutes of fire exposure, how long will these toothpicks stand up? How about the added weight of 2 or 3 firefighters with equipment trying to make a vent hole and removing some of the engineered dead load providing the stability to the system?  Just food for thought. This stuff's out there... It's just a matter of   time 'til it pops up around here. Many nationally recognized instructors are now recommending popping a decent-sized inspection hole in the ceiling immediately inside the point of entry and on each floor of any building with smoke or fire .

Biofluid Mechanics: An Introduction to Fluid Mechanics, Macrocirculation, and Microcirculation shows how fluid mechanics principles can be applied not only to blood circulation, but also to air flow through the lungs, joint lubrication, intraocular fluid movement, renal transport among other specialty circulations. This new second edition increases the breadth and depth of the original by expanding chapters to cover additional biofluid mechanics principles, disease criteria, and medical management of disease, with supporting discussions of the relevance and importance of current research. Calculations related both to the disease and the material covered in the chapter are also now provided. Uses language and math that is appropriate and conducive for undergraduate learning, containing many worked examples and end-of-chapter problemsDevelops all engineering concepts and equations within a biological contextCovers topics in the traditional biofluids curriculum, and addresses other systems in the body that can be described by biofluid mechanics principlesDiscusses clinical applications throughout the book, providing practical applications for the concepts discussedNEW: Additional worked examples with a stronger connection to relevant disease conditions and experimental techniquesNEW: Improved pedagogy, with more end-of-chapter problems, images, tables, and headings, to better facilitate learning and comprehension of the material , Lee Waite and Jerry Fine.
