  2. Torsion (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Torsion_(mechanics)

    Torsion of a square section bar Example of torsion mechanics. In the field of solid mechanics, torsion is the twisting of an object due to an applied torque [1] [2].Torsion could be defined as strain [3] [4] or angular deformation [5], and is measured by the angle a chosen section is rotated from its equilibrium position [6].

  3. Dihedral angle - Wikipedia

    en.wikipedia.org/wiki/Dihedral_angle

    In stereochemistry, a torsion angle is defined as a particular example of a dihedral angle, describing the geometric relation of two parts of a molecule joined by a chemical bond. [ 4 ] [ 5 ] Every set of three non-colinear atoms of a molecule defines a half-plane.

  4. Torsion constant - Wikipedia

    en.wikipedia.org/wiki/Torsion_constant

    The torsion constant or torsion coefficient is a geometrical property of a bar's cross-section. It is involved in the relationship between angle of twist and applied torque along the axis of the bar, for a homogeneous linear elastic bar. The torsion constant, together with material properties and length, describes a bar's torsional stiffness.

  5. Torsion of a curve - Wikipedia

    en.wikipedia.org/wiki/Torsion_of_a_curve

    Geometric relevance: The torsion τ(s) measures the turnaround of the binormal vector. The larger the torsion is, the faster the binormal vector rotates around the axis given by the tangent vector (see graphical illustrations). In the animated figure the rotation of the binormal vector is clearly visible at the peaks of the torsion function.

  6. Torsion spring - Wikipedia

    en.wikipedia.org/wiki/Torsion_spring

    A torsion spring is a spring that works by twisting its end along its axis; that is, a flexible elastic object that stores mechanical energy when it is twisted. When it is twisted, it exerts a torque in the opposite direction, proportional to the amount (angle) it is twisted. There are various types:

  7. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    A bond angle is the angle formed between three atoms across at least two bonds. For four atoms bonded together in a chain, the torsional angle is the angle between the plane formed by the first three atoms and the plane formed by the last three atoms.

  8. Torque - Wikipedia

    en.wikipedia.org/wiki/Torque

    For a rotating object, the linear distance covered at the circumference of rotation is the product of the radius with the angle covered. That is: linear distance = radius × angular distance. And by definition, linear distance = linear speed × time = radius × angular speed × time.

  9. Ramachandran plot - Wikipedia

    en.wikipedia.org/wiki/Ramachandran_plot

    Because dihedral angle values are circular and 0° is the same as 360°, the edges of the Ramachandran plot "wrap" right-to-left and bottom-to-top. For instance, the small strip of allowed values along the lower-left edge of the plot are a continuation of the large, extended-chain region at upper left.
