looking to see if this would be stable or unstable. if it is
stable is it statically determinate or indeterminate?
A biomaterial composite is made of a polymer matrix with aligned ceramic fibre reinforcement. The composite is deformed elastically under an applied stress of applied = 100 MPa along the longitudinal direction (i.e. parallel to the fibres). The elastic modulus of the fibre, Ef, is 200 GPa and that of the matrix, Em, is 5 GPa. The volume fraction of the fibre is Ve = 3.3%. What is the strain experienced by the composite? 0 0.05% O 0.23% 01.10% 0...

Classify the trusses in Figure P4.2 as stable or unstable. If
stable, indicate if determinate or indeterminate. If indeterminate,
indicate the degree.
