[0, 1, 2, 3, 5]; W = 0.25*x + X*x; 1. The MATLAB code will not raise an error: x = true false 2. The MATLAB code sum([1, 1; 0, 2] [1; 6]) results in 1. true false 3. The mathematical model of a structural problem is typically a differential equation. true false 4. The weighted residuals method is an approach to find the exact solution to a differential equation. true false 5. An ansatz for the trial function in the weighted residuals method must have local support (defined on a sub-region). true false 6. In the Galerkin method, test and trial function are the same. true false 7. The weakform implies, that integration by parts has been performed on at least one of the weighted residual expressions. true false 8. Static boundary conditions are considered through the discrete force vector (right hand side) in displacement-based finite elements. true false 9. The term degree of freedom denotes the number of kinematic boundary conditions. true false 10. The local coordinates 2 and of a tensor-product 4-node finite element are defined in the range [0, 2) true false
