Consider a material with measured strength values F given in Table 1.2. Assume the expected stress values to be one-half of the values in Table 1.2. Calculate the safety factor and the reliability of the system.

Example 1.3
Consider the experimental observations of strength reported in Table 1.2 (p. 23). Sort the data into 7 bins of equal width ?S to cover the entire range of the data. Build a histogram reporting the number of observations per bin. Compute the mean, standard deviation, and coefficient of variance. Plot the histogram. Plot the normal probability density function.
