The materials laboratory you direct received the following
tensile strength data in MPa for 15 window glass samples. The data
obtained for each sample are:
Sample Strength (Mpa)
1 32
2. 34
3 36
4 30
5 35
6 37
7 38
8 35.8
9 31.5
10 32.5
11 36.3
12 34.5
13 33
14 36.5
15 33.5
You are asked to calculate the Weibull modulus, m, assuming that
the probability of failure is n/16, where n is the number of
specimens that failed at a given stress.
You can use Excel to speed up the calculations.
Give your answer to one decimal.
