A rectangular bar of length L has a slot in the central half of its length. The bar has width b, thickness t, and elastic modulus E. The slot has width b/3. The overall length of the bar is L = 560 mm, and the elastic modulus of the material is 68 GPa. If the average normal stress in the central portion of the bar is 210 MPa, calculate the overall elongation δ of the bar.
