A balanced orthotropic, or square symmetric lamina, is made up of \(0^{\circ}\) and \(90^{\circ}\) fibers woven into a fabric and bonded together, as shown in Figure 2.10.

a. Describe the stress-strain relationships for such a lamina in terms of the appropriate engineering constants.

b. For a typical glass/epoxy composite lamina of this type, sketch the expected variations of all the engineering constants for the lamina from \(0^{\circ}\) to \(90^{\circ}\). Numerical values are not required.
