the annual stress in sepcific mechanical component follow a weibull cumulative probability distribution of the form: Fx(X)=1-exp-(x/50)^2. Determine the exact distribution for the 20 year maximum stress in this mechanical component. determine also the corresponding asymptotic distribution of the 20-year maximum stress. Then determine the probability of 20 year maximum stress exceeding the value of 100 ksi using both the exact and asymptotic forms.
