Question
Let X denote the vibratory stress (psi) on a wind turbine blade at a particular wind speed in a wind tunnel.
The article, "Blade Fatigue Life AsSsessment with Applications to VAWTS," J. Solar Energy Engr., (1982), pp
107--111, proposes the Rayleigh distribution as a model for the X distribution. Here is the pdf of the model.
i e/(2 0), x> 0,
f(x, 0) =
0,
otherwise.
1 1.1. Suppose that 0= 100 (a value suggested by a graph in the article). What is the probability that X is at
most 200? Less that 200? At least 200?
1.2. What is the probability that X is between 100 and 200, assuming 0 = 100, as before?
1 1.3. Determine the expression of the cdf, F(x, 0) = P(X<x).
