  2. Free body diagram - Wikipedia

    en.wikipedia.org/wiki/Free_body_diagram

    Stresses and strains are of no interest but rotational effects are. A force arrow should lie along the line of force, but where along the line is irrelevant. A force on an extended rigid body is a sliding vector. non-rigid extended. The point of application of a force becomes crucial and has to be indicated on the diagram.

  3. Tension (physics) - Wikipedia

    en.wikipedia.org/wiki/Tension_(physics)

    Tension is the pulling or stretching force transmitted axially along an object such as a string, rope, chain, rod, truss member, or other object, so as to stretch or pull apart the object. In terms of force, it is the opposite of compression. Tension might also be described as the action-reaction pair of forces acting at each end of an object.

  6. Shear force - Wikipedia

    en.wikipedia.org/wiki/Shear_force

    40 tonne-force × 0.6 (to change force from tensile to shear) = 24 tonne-force. When working with a riveted or tensioned bolted joint, the strength comes from friction between the materials bolted together. Bolts are correctly torqued to maintain the friction. The shear force only becomes relevant when the bolts are not torqued.

  7. Pulley - Wikipedia

    en.wikipedia.org/wiki/Pulley

    In this case, a force balance on a free body that includes the load, W, and n supporting sections of a rope with tension T, yields: n T − W = 0. {\displaystyle nT-W=0.} The ratio of the load to the input tension force is the mechanical advantage MA of the pulley system, [ 13 ]

  8. Belt friction - Wikipedia

    en.wikipedia.org/wiki/Belt_friction

    Belt friction is a term describing the friction forces between a belt and a surface, such as a belt wrapped around a bollard.When a force applies a tension to one end of a belt or rope wrapped around a curved surface, the frictional force between the two surfaces increases with the amount of wrap about the curved surface, and only part of that force (or resultant belt tension) is transmitted ...

  9. Rubber band experiment - Wikipedia

    The T-V diagram of the rubber band experiment. The decrease in the temperature of the rubber band in a spontaneous process at ambient temperature can be explained using the Helmholtz free energy = where dF is the change in free energy, dL is the change in length, τ is the tension, dT is the change in temperature and S is the entropy.
