1. The MATLAB code will not raise an error: v = [0,1,2,5]; w=[0,4,5,6); U = v.^3+w"; true false 2. The MATLAB code x=1; f = (2*(x-1)*sin(x*pi/2)/(4*(x-1)) returns 0. true false 3. Linear stress 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 residual function. true false 5. In the weighted residuals method, the number of ansatz functions does not affect the accuracy of the method. 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 false 8. The number of nodes in a finite element mesh is always equal to the number of coefficients used to represent the displacement field. true false 9. The geometric stiffness matrix is involved in linear stress analysis. true false 10. The local coordinates 21 and 22 of a tensor-product 8-nodefinite element are defined in the range [-1, +1]. true false
