Rivets employed to secure the stainless steel sheet metal of the aircraft wings are designed to withstand certain shearing forces. It is known that due to random variations in location the load on the rivet is Weibull distributed with the scale parameter of 750 pounds and the shape parameter of 3.0. The strength of rivets in pounds is also rauted with the sandom due to variations in the material characteristics and dimensional tolerances. It has been found that the strength is also Weibull distribme shape parameter but with the scale The Reliabiliparameter of the 1000 pounds. Let x denote the load on a given rivet and let y denote the strength of that rivet. The rivet will not fail if x is less than y. ty might therefore be expressed as P[X
