Use a computer program to assist in the design problems in Problem 5.72.

For the tripod space frame shown in Figure P5–72, determine standard steel pipe sections such that the maximum bending stress must not exceed 20 ksi, the compressive stress to prevent buckling must not exceed that given by the Euler buckling formula with a factor of safety of 2, and the maximum deflection will not exceed L/360 in any span, L. Assume the three bottom supports to be fixed. All coordinates shown in units of inches.
