Challenge Problems

Push your limits with challenges.

Question 1

A bridge has a mean capacity of 200 tons and a standard deviation of 30 tons. If the mean demand is 190 tons with a standard deviation of 20 tons, determine the reliability index using Taylor's series.

💡 Hint: Remember to calculate the variances using the provided standard deviations.

Question 2

In a Monte Carlo simulation of a support beam with random variables related to its materials and loads, how would you assess the failure probability after 1,000 trials showing 50 failures?

💡 Hint: Think of how the ratio of failures to total scenarios represents the risk.
