Vehicle speed on a particular bridge in China can be modeled as normally distributed (“Fatigue Reliability Assessment for Long-Span Bridges under Combined Dynamic Loads from Winds and Vehicles,” J. of Bridge Engr., 2013: 735–747). If of all vehicles travel less than and travel more than , what are the mean and standard deviation of vehicle speed? [Note: The resulting values should agree with those given in the cited article.] Answer What is the probability that a randomly selected vehicle’s speed is between and ? Answer What is the probability that a randomly selected vehicle’s speed exceeds the speed limit of ?

Q: A 100kg man walks at 3mi/hr for 1hr. How many calories does he expend over resting? Hint: Follow these steps (From page 120 of the book) Metabolic Cost of Walking 1. Convert mi/hr to m/min. 2. Multiply that number by 0.1ml/kg/min 3. Add 3.5ml/kg/min 4. Multiply that number by the mass of the person (100kg) and then the pace (20min/mi) 5. You should have units of ml/mi. Convert that to L/mi. 6. You now should have the O2 cost of walking at that pace. 7. Multiply that number by 5kcal/L. You should now have the metabolic cost of walking in kcal/mi 8. Multiply that by the distance that the man walked, and you will have the Total kcal burned. Metabolic Cost at Rest 1. Resting O2 is 3.5ml/kg/min. Multiply that by the mass of the person. 2. Multiply that number by the total time of the walk in min. 3. Convert that number to L. 4. Multiply that number by 5kcal/L to get the metabolic cost of an equivalent amount of rest. Net Metabolic Cost 1. Subtract Metabolic Cost at Rest from the Metabolic Cost of Walking to get the Net kcal's burned!
