The weight P in pounds that a beam can safely carry is inversely proportional to the distance D in feet between the support beams. for a certain type of wooden beam, p=9200/
d. what distance between supports is needed to carry 1600 lb
Rewriting the function we have: p = 9200 / D We must in this case clear the value of D. We have then: D = 9200 / p Substituting the value of p = 1600 lb we have: D = 9200/1600 D = 5.75 feet Answer: the distance between supports that is needed to carry 1600 lb is: D = 5.75 feet
