This formula uses 6 Variables
Variables Used
End Prestress Force - (Measured in Newton) - End Prestress Force refers to the applied prestressing force at the stretching end of tendon.
Prestress Force at a Distance - (Measured in Newton) - Prestress Force at a Distance refers to the force on prestressed section at a distance x from stretching end.
Prestress Friction Coefficient - The Prestress Friction Coefficient (μ) is the ratio defining the force that resists the motion of one body in relation to another body in contact with it.
Cumulative Angle - (Measured in Radian) - Cumulative Angle here refers to the angle in radian through which the tangent to the cable profile has turned between any two points under consideration.
Wobble Coefficient - Wobble Coefficient is found by multiplying the jacking force at any distance from jacking end with the average of the intended angular deviation from the design profile.
Distance from Left End - (Measured in Meter) - Distance from Left End is the distance considered from the left jacking end on a prestressed member.
STEP 1: Convert Input(s) to Base Unit
Prestress Force at a Distance: 96 Kilonewton --> 96000 Newton (Check conversion here)
Prestress Friction Coefficient: 0.067 --> No Conversion Required

What is meant by Vertical or Transverse Prestresisng?

Besides the longitudinal prestressing sometimes it may be desirable to provide vertical prestresisng to reduce or eliminate the principal tensile stress. Vertical prestressing is done by providing high tension vertical steel wires of small diameter at suitable pitch & stressed adequately.
