Assumming appropriate SW's and FW's, yes.

This is also affirmative... in as much as Terry's question is posed in the
perspective of a constant BW value and an appropriate SW curve. Different ways
of saying basically the same thing.

Once again... BW + FW on the one side of the balance rail pin,....  SW, leverage
and friction on the other side.
