Exercises problems for structural engineering 1. when estimating the live load for a new bridge design, you want that estimate to be conservative. in other words, you want to err on the safe side by basing the estimate on the worst possible scenario, such as bumper-to-bumper traffic, the heaviest vehicles, or the worst environmental conditions. with this in mind, estimate the live load for the following proposed bridge designs.
a. a foot bridge with a 174. ft span and two separate 4. ft wide lanes to allow for pedestrian traffic in both directions.
b. a four-lane highway bridge with a 300. ft span.

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
