A prestressed concrete beam of rectangular section 300mm wide and 600mm deep is prestressed by 5 pieces of 8mm high tensile wires at 500mm from the top and 15 pieces of 8mm diameter high tensile wires at 83 mm from the bottom. The initial stress in the wires is 1200 MPa. Estimate the loss of stress in the bottom wires due to elastic shortening of concrete. Assume modular ratio = 6.
