Homework Statement
A partially loaded plane weighs 115,000 pounds. A famous actor's steamer trunk, weighing 300 pounds, is put into the rear cargo hold 250 inches behind the center of gravity. How much does this extra hold shift the center of gravity.
Homework Equations
W1 = W x (L2 / L)
W2 = W x (L1 / L)
W = 115300
W1 = 115000
W2 = 300
L = 250
The Attempt at a Solution
I did this:
W2 = W x (L1 / L)
so...
300 = 115300 x (L1 / 250)
so...
300 = 461.2L1
divide both sides by 461.2
L1 = .6504770165
The center of gravity of the plane shifts .6504770165 inches toward the rear. Your input is encouraged.
