2.1 Use the direct iteration method to solve the following one degree of freedom problem, H+f = 0 where f = 10 and H depends on according to H = 10(1+e3e). 2.2 Repeat Problem 2.1 using the Newton-Raphson method. Compare the solutions and the computational effort required in each. 2.3 Solve the following one degree of freedom problem by both the tan- gential stiffness and initial stiffness method. Apply the total load f as two equal increments H+f = 0, f = 10, H = 20(1-4). 2.1 Use the direct iteration method to solve the following one degree of freedom problem, H+f = 0 where f = 10 and H depends on according to H = 10(1+e3e). 2.2 Repeat Problem 2.1 using the Newton-Raphson method.
