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.
