The vertical posts are supported by planks of the dam post with cross-section bx b. The spacing of the posts are s = 0.8m with the water level at h = 2m.

I need help on this question: a) Find strain energy for truss AC. The answer should be in J to 2 decimal places. (positive value indicates tension, negative value compression) b) Find strain energy for truss AB. The answer should be in J to 2 decimal places. (positive value indicates tension, negative value compression) c) Find Strain energy for truss BC. The answer should be in J to 2 decimal places. (positive value indicates tension, negative value compression)
