The weight that can be safely supported by a 2 by 6 inch support beam varies inversely with its length.
w = k/L
-----------------
Solve for "k" using "A builder finds that's support beam that is 6 feet long will support 900 pounds."
900 = k/6
k = 5400
---
Equation:
w = 5400/L
Find the weight that can be safely supported by a beam that is 18 feet long.
w = 5400/18
w = 300 lbs
The weight that can be supported by the beam is 300 lbs ?
