Q. 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 = 2×104 kNm2 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
Ans: 0.10 – 0.12
