Civil Engineering > GATE 2020 SET-2 > Prestressed Concrete
A concrete beam of span 15 m, 150 mm wide and 350 mm deep is prestressed with a parabolic cable as shown in the figure (not drawn to the scale). Coefficient of friction for the cable is 0.35, and coefficient of wave effect is 0.0015 per meter.
If the cable is tensioned from one end only, the percentage loss (round off to one decimal place) in the cable force due to friction, is _______.
Correct : 3.8 to 4.7
