In the steady state a good weather vane points into the wind, but when the wind shifts, the vane cannot always be trusted to be pointing into the wind. identify inputs, outputs, and the parameters of the weather vane system that affect its response to the wind. sketch your idea of how the position of the vane would change in time if the wind suddenly shifted 10◦ .
