Suppose you were planning to move a house by transporting it on a large trailer. The house has an estimated weight of 47.7 tons. The trailer is expected to weigh 6.8 tons. Each wheel of the trailer will have tires inflated to a gauge pressure of 85 psi (which is actually 85 psi above atmospheric pressure). If the area of contact between a tire and the pavement can be no larger than 100.0 in? (10.0 in.x 10.0 in.), what is the minimum number of wheels that trailer must have? (Tires are mounted in multiples of 2 on a trailer. Assume the atmospheric pressure is 14.7 psi.) # of tires = i tires
