  2. Necking (engineering) - Wikipedia

    en.wikipedia.org/wiki/Necking_(engineering)

    Because the local strains in the neck are large, necking is often closely associated with yielding, a form of plastic deformation associated with ductile materials, often metals or polymers. [1] Once necking has begun, the neck becomes the exclusive location of yielding in the material, as the reduced area gives the neck the largest local stress.

  3. Sauropod neck posture - Wikipedia

    en.wikipedia.org/wiki/Sauropod_neck_posture

    Sauropod neck posture is a subject occasionally debated among scientists, with some favoring postures closer to horizontal whilst others a more upright posture. Research has looked at various avenues of evidence and analysis including: attempting to reconstruct the neutral posture of their necks and estimating range of motion by studying the ...

  4. Spinal posture - Wikipedia

    en.wikipedia.org/wiki/Spinal_posture

    Looking directly at the front or back of the body, the 33 vertebrae in the spinal column should appear completely vertical. From a side view, the cervical (neck) region of the spine (C1–C7) is bent inward, the thoracic (upper back) region (T1–T12) bends outward, and the lumbar (lower back) region (L1–L5) bends inward.

  5. Neck - Wikipedia

    en.wikipedia.org/wiki/Neck

    The neck is the part of the body in many vertebrates that connects the head to the torso. It supports the weight of the head and protects the nerves that transmit sensory and motor information between the brain and the rest of the body. Additionally, the neck is highly flexible, allowing the head to turn and move in all directions.

  6. Stress–strain curve - Wikipedia

    en.wikipedia.org/wiki/Stress–strain_curve

    After the neck has formed in the material, further plastic deformation is concentrated in the neck while the remainder of the material undergoes elastic contraction owing to the decrease in tensile force. The stress–strain curve for a ductile material can be approximated using the Ramberg–Osgood equation. [2]

    You may have also heard the term ‘tech neck,’ which refers to horizontal fine lines that stretch across the neck. The moniker comes from the cause: constantly looking down at you phone.

  8. Rounded shoulder posture - Wikipedia

    en.wikipedia.org/wiki/Rounded_shoulder_posture

    Symptoms of RSP will lead to upper back stiffness, neck stiffness and shoulder stiffness. [1] It can be diagnosed by several tests, including physical tests [5] and imaging tests. [5] To prevent RSP from worsening, maintaining a proper posture, [citation needed] doing regular exercise, [6] and undergoing therapeutic treatments [7] could be ...
