Form the distribution curves $($quantitative analysis$)$ based on numerical data for the most critical aspects of wind turbine rotor blades and pitch mechanism. Calculate the failure probability by using two overlapping distributions. If it is possible then form several distribution analyses in an analogical way. For Quantitative analysis, try to find some data from the internet as a reference and put them in the content. Use your word$/$figures$/$charts$/$tables to explain, you can draw the figure using Matlab. Please also give reference.
