Of course it is stable. But where is the center of gravity. It is (16; 0.5), isn't it?

Just 16, z-coordinate doesn't matter (-)

It means that the center of gravity is determined by only x-coordinate, isn't it?

It dosen't mathers the y coordinate because there is no force to move bricks left or right, just gravity to move then bottom. the center is 16.

Yes, it is (-)

This configuration is unstable. My program "says" that the center of gravity is 1.5. Is it right?
If it is then it is support brick and system is stable.
What's wrong?
Pleasse, help!!!

BIG-BIG-BIG THANKS TO EVERYBODY!!! I'VE GOT ACCEPTED!!!
