Fracture is a type of material failure. Of the following which is another type of material failure? - Permanent deformation. Which of the following statements best differentiates between a defect and a discontinuity? - Discontinuities can propagate and become defects. Nondestructive testing is often differentiated from other measurements or inspection techniques in that: - NDT involves indirect tests related to some other quality or characteristic of material. What are the functions of ...

Musculoskeletal Flexibility The ability to move a joint freely through its full ROM the incidence of "Lower Back Pain" in the United States 75 million; 80% is attributed to flexibility What is the primary cause of lower back pain? Low Flexibility Describe Elastic Deformation Results in a temporary and reversible change in length of tissue (Rubberband) Describe Plastic Deformation Occurs when tissue is stretched beyond the elastic component of the tissue. It results in relatively pe...
