Calculate the corresponding stress level

Question

Solve the following problem:

For sample type 5 in Table , calculate the strain at position x = aw/4, y = af /2 for the case of a longitudinal tensile load N_x = 5 N/mm using the bending-restrained model.

Calculate the corresponding stress level in fill and warp, at the same location, in material coordinate system.

Determine if any kind of failure takes place at this load level.
