During a study, it was discovered that each lane of a highway saw 2100 two-axle trucks every day. Determine the number of standard axle load repetitions (in million) during a design life of 10 years assuming the vehicle damage factor and growth factor are 5 and 7.5 percent, respectively.
The figure shows a top view of an intersection where a traffic accident occurred. Vehicle 1 was traveling eastward while Vehicle 2, traveling northward, ran through a stop sign and crashed into Vehicle 1. The collision was violent. As the vehicles crushed, they became entangled and moved as one, sliding across the intersection and leaving the road. Here are some technical details of the accident: • Vehicle 2 was larger, weighing 50% more than Vehicle 1. • According to a driver following Vehicle 1, it was traveling at the posted speed limit. • Both streets had the same speed limit. It is not known how fast Vehicle 2 was traveling. • The collision caused Vehicle 1 to divert its path by an angle of 0 = 60°, as shown in the figure. • The street was covered with snow and ice, making conditions very slippery. Use the information above to answer the following questions. (I'm expecting the first question to be fairly straightforward, and the second question to be more tricky.) 1. We know that…
