QUESTION 1 One PhD student have developed simulation model for calculating the young's modulus of wood plastic composite (WPC), (Equation-. The strength of the composite depends on the volume fraction of wood fiber and the plastic matrix. Solve the problem using symbolic functions and replace the numerical values to get the answer Eq-1 Where x = 0.8 Ec-Youngs modulus of the composite MPa Ec-Youngs modulus of the composite MPa Ec-Youngs modulus of the composite MPa Vf 0.3 Vm= 1-vf is the volume fraction of the matrix Attach the matlab program. marks) (10
