Unformatted text preview: http://www.youtube.com/watch?v=Hqqc6gfVrtU&feature=related The dynamics of one type of flyball governor can be analyzed by reference to Figure 2 Using FBD on W, in z (vertical) direction (where down is +) under steady speed: (1) From a FBD on w, in z direction: (2) From FBD on w, in the n direction (in is +): (3) There are three equations in 3 unknowns. By eliminating T 1 and T 2 one can derive: (4) This can be solved for given weights, lengths and rotational speed by trial and error, guessing α. This can also be done in Excel by rearranging Equation (4) to get Equation (5), which must be close to zero. Excel’s Solver can make this easy. < Flyball governor.xlsx > (5)...
