For the tripod distance mould shown in Figure P5–72, determine standard steel pipe sections such that the completion fawning emphasis must not surpass 20 ksi, the compressive emphasis to forefend buckling must not surpass that given by the Euler buckling formula delay a ingredient of security of 2, and the completion alienation get not surpass L/360 in any two, L. Assume the three bottom supports to be unroving. All coordinates shown in units of inches.
