    A Force Related To The Stretching of An Object (The Opposite of Compression)

    Uploaded by

    Victor Diaz Roldan
    This document discusses different types of forces and deformations: 1. Tension causes stretching, compression causes squashing, bending causes bending, shear causes scissoring, and torsion causes twisting. 2. Bending in a beam puts the lower half in tension and the upper half in compression, with stresses reaching their maximum at the surfaces and decreasing to zero at the neutral axis. 3. Shear refers to parallel internal surfaces sliding past each other due to an applied shear stress, while torsion is the twisting of an object due to an applied torque.

    Force, deformation and Failure

    Types of force and deformation

    Non-technical word Technical term (noun) Adjective used with Initial deformation of
    the nouns stress, load component or member
    and force
    stretching tension tensile stress It will extend (lengthen).
    squashing compression compressive stress It will compress
    (shorten).
    bending bending bending stress It will bend – we can
    also say it will deflect or
    flex. Beams usually sag,
    deflecting downwards.
    In some cases deflection
    or flexure is upward- the
    beam hogs.
    scissoring shear or shearing shear stress It will deform very little,
    failing suddenly.
    twisting torsion or torque torsional stress It will twist.

     Tension: a force related to the stretching of an object (the opposite of compression).

    Tension

     Compression: the result of the subjection of a material to compressive stress.

    Compression

    Bending: In applied mechanics, bending (also known as flexure) characterizes the


    behavior of a slender structural element subjected to an external load applied
    perpendicularly to a longitudinal axis of the element.

    Bending

     Shear or Shearing: Shearing in continuum mechanics refers to the occurrence of a shear


    strain, which is a deformation of a material substance in which parallel internal surfaces
    slide past one another. It is induced by a shear stress in the material.

    Shear or Shearing
     Torsion or Torque: torsion is the twisting of an object due to an applied torque.

    Torsion or Torque

    Bending comprises two opposite stresses: tension and compression. This is shown in the diagram
    of a simply supported beam. As a result of the bending force, the lower half of the beam is in
    tension and upper half is in compression. These opposite stresses reach their maximum at the
    upper and lower surfaces of the beam, and progressively decrease to zero at the neutral axis- an
    imaginary line along the centre of the beam which is free from stress.
