**bobpursley**, Friday, April 29, 2011 at 8:55pmdraw the figure, with the hinges, and the center of gravity.

Write sum of moments about the hinges.

Here is the equation from the lower hinge:

.40meter*Weight-2.1meter*Fupperhinge=0

That gives you Fupperhinge. Do the same for the other hing, but I bet a coke it is = - Fupperhinge.

check my math.
