The weight P is inversely proportional to the distance D, so we can set up the equation:
P = k/D
where k is the constant of proportionality.
Given that P = 8000/D, we can plug in P = 2000 and solve for D:
2000 = 8000/D
D = 8000/2000
D = 4 feet
Therefore, the distance between the supports needed to carry 2000 lb is 4 feet.
