A pile resists the tension developed by three stay cables for a major for a tent (membrane) structure. Assuming no bending is desired in the pile (no resultant horizontal componenet), what is the magnitude of the force S if the and (theta sub S) = 30 degrees? If the pile resists with a capacit of 500# per square foot of embedded surface, what is the penetration h for the pile? 1"=8k.
