1. The MATLAB code will not raise an error: v = [0,1,2,5]; w=[0;4;5;6]; u = V13+w'; true false 2. The MATLAB code x=1; f = (2*(x-1)*sin(x*pi/2))/(4*(x-1)) returns 1/2. true false 3. Linear stability analysis of a structural problem involves the solution of an eigenvalue problem. true false 4. In the least-squares method, the test function is identical to the trial function. true false 5. In the weighted residuals method, the shape of ansatz functions does not affect the accuracy of the method. false true false 6. The weak form implies, that integration by parts involves the use of Neumann boundary condition on at least one of the weigthed residual expressions. true false 7. The Dirichlet boundary condition can be imposed at algebraic level, modifying the discrete matrix and discrete force vector in the displacement-based formulation true 8. The number of finite elements denotes the number of coefficents used to represent the displace- ment field. true false 9. The geometric stiffness matrix is involved in linear stress analysis. true false 10. The local coordinates 21 and 2 of a tensor-product 4-node finite element are defined in the range [-1,+1) true false
