Q2). (70 pts) A [0/90/0/445]s Glass/Epoxy laminate is subjected to the following mechanical loads: Nx=Ny=Kx105N/m. The thickness of each lamina is 0.25mm. a) Determine the local stresses at the top of 45ply. b) Determine the percentage of the load taken by each plies? Use the properties of a unidirectional Glass/Epoxy lamina from Table 2.1 TABLE 2.1 Typical Mechanical Properties of a Unidirectional Lamina (SI System of Units)
