If I am not too stupid and I write the equations "naturally", I … SpletThe mass matrix is (3.19) which is a diagonal matrix with the mass and inertia tensor along the block diagonal. The mass matrix for the first linkage (i = 1, e.g. the wings) is given in (3.20), and should a second linkage ( i = 2, e.g. the four-bar mechanism, tail surface, etc.) need to be modeled, the mass matrix is given in (3.21). steelers vs bengals game today score
