Fracture in vertebrae subjected to extreme stresses?
compression
What fracture in vertebrae is subjected to extreme stresses?
Compression Fracture
What are the major stresses to which all aircraft are subjected?
Bending, Shearing, Torsion, Shearing, and Compression.
What is affected by airplanes speed?
Lift(carrying capacity), fuel economy, stresses on the air frame, temperature the air frame is exposed to.
What type of connective tissue that strengthens and supports areas subjected to stresses from many directions?
Dense irregular connective tissue
What has the author Peter Alexander McKenna written?
Peter Alexander McKenna has written: 'Fatigue of ferrous metals subjected to direct alternating stresses'
When a horizontally laid out of beam is subjected to a vertical load which part expresses compressive stresses?
If the load is from the top pointing down, compessive stress is at the top and tension at the bottom
When i have grinded on my bmx bike i have grinded on my frame and its wearing my frame down i was wonding if you had any advice because its wearing away my frame?
uhhm the only thing i would say its that if you want to keep your frame, stop doing that. if your frame becomes damaged, you should replace it. if theres a worn down part of the frame, it will be a point that can fracture from the stresses of BMX riding because it will be weaker than the surrounding areas on the frame.
What is difference between von mises and principle stress?
Whenever an elastic body subjected to loads in its 3 dimensions, the stresses will get developed along the principal axis of the body. These are the principal stresses. These stress should not exceed the yield stress of the material. Von Mises (1913) postulated that, even though none of the principal stresses exceeds the yield stress of the material, it is possible for yielding of the same from the combination of stresses. The Von Mises criterion is a formula (refer any textbook which content failure theories for Ductile Materials) for combining these 3 stresses into an equivalent stress, which is then compared to the yield stress of the material.
Why is symmetry important in truss structures?
Stresses will be distributed equally among members if there is symmetry. It will be easier to calculate it will be easier to manufacture...
What is plastic memory?
If certain plastics (take for instance PTFE) is subjected to stresses below its yield point then it may be subjected to permanent deformation. This deformation will induce certain strains through out the material. If the plastic is heated up, these strains tend to relax which allows the plastic to return to its original shape. This is often refered to as "plastic memory".
What is Electric field stress?
An Electric field stress depends on the mechanical strength of the materials and the stresses that are generated during their operation. During high voltage applications, the dielectric strength of insulating materials are developed when subjected to high voltages.
