Infrared spectroscopy measures the vibration of molecules, including stretching, bending or twisting motions. This bending moment resists the sagging deformation characteristic of a beam experiencing bending. The flexors allow for the actual bending of the fingers. Her right arm is capable of bending steel or throwing objects great distances. It forms rigid nucleoprotein filaments causing the straitening of DNA and not the bending. Single plane resistance exercises against cervical flexion, extension, bending, and rotation are used. Facet joints appear to have little influence on the range of side bending (lateral flexion). Cockles are capable of "jumping" by bending and straightening the foot. It is also used in punching and bending operations. Usually, attempting to deform bulk diamond crystal by tension or bending results in brittle fracture. Which chord carries tension and which carries compression depends on the overall direction of bending. HeN is tough enough to have several vibrational, bending and rotational states. Refraction is another kind of sound wave bending. Beams are elements which carry pure bending only. This includes things such as bending and breaking rules, cheating, and stealing.
