  2. Capstan equation - Wikipedia

    en.wikipedia.org/wiki/Capstan_equation

    where is the applied tension on the line, is the resulting force exerted at the other side of the capstan, is the coefficient of friction between the rope and capstan materials, and is the total angle swept by all turns of the rope, measured in radians (i.e., with one full turn the angle =).

  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.

  4. Block and tackle - Wikipedia

    en.wikipedia.org/wiki/Block_and_tackle

    A block and tackle is characterized by the use of a single continuous rope to transmit a tension force around one or more pulleys to lift or move a load. Its mechanical advantage is the number of parts of the rope that act on the load. The mechanical advantage of a tackle dictates how much easier it is to haul or lift the load.

  5. 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 ...

  6. Rolling hitch - Wikipedia

    en.wikipedia.org/wiki/Rolling_hitch

    The rolling hitch is a knot (see also Magnus hitch) used to attach a rope to a rod, pole, or another rope. A simple friction hitch, it is used for lengthwise pull along an object rather than at right angles. The rolling hitch is designed to resist lengthwise movement for only a single direction of pull.

  7. Hooke's law - Wikipedia

    en.wikipedia.org/wiki/Hooke's_law

    In physics, Hooke's law is an empirical law which states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring.

  8. Tape correction (surveying) - Wikipedia

    en.wikipedia.org/wiki/Tape_correction_(surveying)

    Some tapes are already calibrated to account for the sag at a standard tension. [1] [2] In this case, errors arise when the tape is pulled at a Tension which differs from the standard tension used at standardization. The tape will pulled less than its standard length when a tension less than the standard tension is applied, making the tape too ...

  9. Stiffness - Wikipedia

    en.wikipedia.org/wiki/Stiffness

    The skin maintains its structure due to its intrinsic tension, contributed to by collagen, an extracellular protein that accounts for approximately 75% of its dry weight. [5] The pliability of skin is a parameter of interest that represents its firmness and extensibility, encompassing characteristics such as elasticity, stiffness, and adherence.
