10a. Waclaw Zalewski and Edward Allen, "Finding Forms and Forces for Funicular Structures," Shaping Structures: Statics

1. What is the horizontal conponent of the cable forces shown in figure 8.1, and is it constant throughout the cable?

2. Optional: Based on the equilibrium of joints "b," "c," and "d" shown in figure 8.2 (p. 177), are there any upper and lower limits on the weight that can be applied to the pulley at "A"?

3. What is the definition of a "funicular polygon?"

4. What are two methods of cutting a cable, while preserving the shape and structural behavior of the cable piece that remains? Draw diagrams if necessary.

5. How many different funicular shapes are possible for a given set of loads where the horizontal distance between loads is held constant?
