An 18-m-long steel wire of 10-mm diameter is to be used in the manufacture of a prestressed concrete beam. It is observed that the wire stretches 55 mm when a tensile force P is applied. Knowing that E=250 GPa, determine (a) the magnitude of the force P, (b) the corresponding normal stress in the wire
