Question
Suppose you were planning to move a house by transporting it on a large trailer.
The house has an estimated weight of 52.3 tons. The trailer is expected to weigh 6.4 tons.
Each wheel of the trailer will have tires inflated to a gauge pressure of 86 psi (which is actually 86 psi above atmospheric pressure). If
the area of contact between a tire and the pavement can be no larger than 100.0 in² (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
