Final answer:
The longitudinal strength of a fiber composite can be computed by analyzing its resistance along its length, using factors such as material properties, tensile stress and strain, and Young's modulus.
Step-by-step explanation:
The longitudinal strength of a fiber composite can be computed by analyzing its resistance along its length. This involves considering factors such as the material properties, tensile stress and strain, and Young's modulus. The change in length, applied force, and cross-sectional area are also important in the computation of longitudinal strength.
