For Problem 4-41 from the 11th edition: 1. Assign a fictious load at point C acting upwards. 2. Find the equation for the strain energy due to Fy. Do not assign numerical values to any of the forces. 3. Enter the equation for strain energy into Matlab. 4. Have MatLab find the derivative of the strain energy from (3) with respect to the force at C. This is Catigliano’s Thm. 5. Set the force at C equal to zero and Fy = 200 LB upwards. All other forces at point D are Zero. 6. Determine the displacement of C in the Y direction.
