Calculate the shear modulus for steel in GPa, if given that young modulus is 215 GPa and possion’s ratio is 0.33?

Correct Answer: 80 GPa
The relation between young modulus and poison’s ratio is: => E=2G(1+ν) E=215 GPa, ν=0.33 => 215=2*G(1+0.33) => G=80.82 GPa.

Graphite fibres are used to make undirectional Al-matrix composites. Young's modulus of graphite and aluminium are 400 GPa respectively. If a composite contains 60 volume % of fiber and is loaded along the fiber direction, the Youngs Modulus of the composite is . . . . . . . . GPa.

A glass reinforced polymer composite comprises of 35 volume % glass fiber and 65 volume % of polymer resin. The elastic moduli of glass and polymer resin are respectively 70 GPa and 3 GPa. The elastic modulus of the composite (in GPa) under iso-strain state is
