Question 45
On paper, classify each complete set of cables as removable or not removable: a. A, C, D; b. B, C, D; c. C, A; d. D, B; e. A, B, C. The source labels these Non-essential/Essential. Use an ideal rigid beam pinned to the post, with taut cables that pull but cannot push and adequate strength. This is a diagram model, not permission to remove real support cables.
