X A cylindrical part of diameter "d" is loaded in tension by a load "P" causing a stress: a-P/A. The load has an uncertainty of 15 percent, the diameter has an uncertainty of 75 percent, and the stress has an uncertainty of 15 percent. Determine the minimum design factor that will guarantee the non-failure of the part to three significant figures.
