GATE Civil 2012 | Question: 33
A concrete beam prestressed with a parabolic tendon is shown in the sketch. The eccentricity of the tendon is measured from the centroid of the cross-section. The applied prestressing force at service is $1620$ kN. The uniformly distributed load of $45$ kN/m ... in the bottom fibre at mid-span is tensile $2.90$ compressive $2.90$ tensile $4.32$ compressive $4.32$

A $6$ m long simply-supported beam is prestressed as shown in the figure. The beam carries a uniformly distributed load of $6$ kN/m over its entire span. If the effective flexural rigidity $EI=2 \times 10^4 \: kNm^2$ and the effective prestressing force is $200$ kN, the net increase in length of the prestressing cable (in mm, up to two decimal places) is _____
