The maximum load that a horizontal beam can carry is directly proportional to its width. If a beam 1.5 inches wide can support a load of 250 pounds, find the load that a beam of the same type can support if its width is 3.5 inches.
----------------
L = kw
--
Solve for "k" using "a beam 1.5 inches wide
can support a load of 250 pounds"
---
250 = k*1.5
k = 166.67
-----
Equation: L = 166.67w
----
Find the load that a beam of the same
type can support if its width is 3.5 inches.
---
L = 166.67*3.5
L = 593 1/3 lbs.
