A 1.2m long concrete beam has a cross-sectional area of 0.05m2.
The beam is reinforced by 4 embedded steel bars, each 19mm in diameter, as shown in Figure Q5.
Calculate the stresses in the steel and concrete when a tensile load of 250kN
is applied to the beam.
For concrete E = 25GPa, steel E = 210GPa.
Please help!

.Discretise the integral in terms of the steel and concrete volume fractions:
.The final two steps are trivial. Use the equation
and the fact that the strain must be identical in both constituents and you should get very close to your answer.
