A

B

C

D

E

ANS:C -

The tension ratio (TR) at a distance x from either end of the tendon can be calculated using the Wobble Correction Method, which incorporates the effects of curvature and friction. The equation for tension ratio (TR) is given by: TR=e kμ /R ​x Where:

  • k is the wobble correction factor.
  • μ is the coefficient of friction between the duct surface and the curve of the tendon.
  • R is the radius of curvature of the tendon.
  • x is the distance from either end.
This equation describes how the tension in the tendon varies along its length due to the combined effects of wobble and friction. Please note that this equation assumes a simplified scenario and may need further adjustment depending on the specific details of the tendon's geometry, loading conditions, and other factors.
