Determine the:1- density 2-The mass Fraction for both 3-The transverse youngs modulus of almuinum/graphite 4-The axial youngs modulus of the almunium/graphite Given:aluminum pm=0.0027g/mm³ E1m=E2m=70Gpa Graphite p1=0.0018g/mm³ E1f=220Gpa E2f=20Gpa
Q1: A rod made of carbon reinforced epoxy has a diameter 3 cm, length 1.5 m, and
mass 1.75 kg. The carbon fibers have a modulus of elasticity 340 GPA and a
density 1.91 g/cm³. The epoxy matrix has a modulus of elasticity 4 GPA and a
density 1.16 g/cm'. Assume there are no voids in the rod.
