Limit of economic haul is 450 m.

How many trips would one rubber-tired Herrywampus haveto make to backfill a space with a geometrical volume of5,400 cubic yard? The maximum capacity of the machine is30 cubic yard (heaped), or 40 tons. The material is to becompacted with a shrinkage of 25% (relative to bank measure)and has a swell factor of 20% (relative to bank measure).The material weighs 3,000 lb/cu yd (bank). Assumethat the machine carries its maximum load on each trip.Check by both weight and volume limitations.

Consider a Bridge crossing 4,719 feet where the weight function is given by W = 3.2S + 30.5, the span cost amount is 2.8 $/pound and the pier placement cost is 14,979 Dollars per pier or abutment. Find the the practical optimum span length in feet. Hint, round to nearest number of integer pier spaces.
