Determine the expected extension at the jack, Civil Engineering

Assignment Help:

A cylindrical concrete tank, 30 m external diameter, is to be prestressed circumferentially by means of  high-strength steel wire (E, = 2 x  105  N/mm2)  jacked  at 4 points, 900 apart. If  the minimum stress  in the wire immediately after tensioning is to be 450 N/mm2  and coefficient of friction is 0.5, calculate :

(a) The maximum stress to be applied to the wires at the  jack, and

(b) The expected extension at  the jack.
