Derivation of torsion formula

WebThen I will describe how the adjoint twisted Reidemeister torsion shows up in the asymptotic expansion of the invariants. Especially, we find new explicit formulas for the adjoint twisted Reidemeister torsion of the fundamental shadow link complements and of the 3-manifolds obtained by doing hyperbolic Dehn-filling on those link complements. WebFeb 3, 2024 · This calculation is done in Deriving the Shear Modulus S From the Torsion Constant κ. The result is κ = η π r 4 2 L in which r is the radius of the wire and L its length. Substituting into the equation for the period we get T = 2 π 2 L I η π r 4 which is the formula you were given. Note

In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. Torsion is expressed in either the pascal (Pa), an SI unit for newtons per square metre, or in pounds per square inch (psi) while torque is expressed in newton metres (N·m) or foot-pound force (ft·lbf). In sections perpendicular to the torque axis, the resultant shear stress in this section is per… WebDec 21, 2024 · By definition of v we have γ ′ = v T. The second derivative of γ is γ ″ = v ′ T + v T ′ = v ′ T + v 2 κ N. The cross product γ ′ × γ ″ becomes γ ′ × γ ″ = κ v 3 B. If we take the norm of both sides, we obtain (1) κ = ‖ γ ′ × γ ″ ‖ v 3 = ‖ γ ′ × γ ″ ‖ ‖ γ ′ ‖ 3. The binormal vector B is a unit vector perpendicular to T and N.
