Given the derivations you have done, and the moduli calculated for the same material under isostrain conditions and isostress conditions in Questions 1 & 2, which of the following diagrams do you think would give the best stiffness?

Question

Answer

Diagram 3 where all the fibres are aligned parallel to the loading direction.

Answer

Stiffness is highest when the fibres are arranged randomly.

Answer

Daigram 2 where all fibrers are aligned perpendicular to the loading direction

Answer

Diagram 4 where 50% of the fibres are aligned parallel and 50% are aligned perpendicular to the loading direction.

Answer

Diagram 1 where 50% of the fibres are aligned at 45 degrees to the right and 50% are aligned at 45 degrees to the left of the loading direction.
