Acylindrical part of diameter d is loaded by an axial force p. this causes a stress of p/a, where a = πd2/4. if the load is known with an uncertainty of ±10 percent, the diameter is known within ±3 percent (tolerances), and the stress that causes failure (strength) is known within ±16 percent, determine the minimum design factor that will guarantee that the part will not fail.
