Prestressed concrete beams are sometimes manufactured in the following manner. High-strength steel wires are stretched by a jacking mechanism that applies a force Q, as represented schematically in part a of the figure. Concrete is then poured around the wires to form a beam, as shown in the figure part b. After the concrete sets properly, the jacks are released, and the force Q is removed (see part c of the figure). Thus, the beam is left in a prestressed condition with the wires in tension and the concrete in compression. Assume that the prestressing force Q produces in the steel wires an initial stress a0= 620 MPa. If the module of elasticity of the steel and concrete are in the ratio 12:1 and the cross-sectional areas are in the ratio 1:50. what are the final stresses a5and a5 in the two materials?
