Laminate lay-up for high shear stiffness and low Poisson's ratio

[mattyboson12]

Homework Statement

a)Describe a potential laminate lay-up that would exhibit high shear stiffness
b)Describe a potential laminate lay-up that would exhibit a low poissons ratio

The Attempt at a Solution

a) is a unidirectional lay-up in the direction of the shear force best?
b) an evenly layup cross-ply?

The question isn't worded very well, but you have the right idea. For (a), they are probably looking for you to say to use 45 degree cross plies.
