The description of rigid-body rotation is greatly facilitated by transforming from the space-fixed coordinate frame (ˆx, ˆy, ˆz) to a rotating body-fixed coordinate frame (ˆ1, ˆ2, ˆ3) for which the inertia tensor is diagonal. Appendix 19.4 introduced the rotation matrix {λ} which can be used to rotate between the ...

WebMar 14, 2024 · However, for a rigid body, the velocity of a body-fixed point with respect to the body is zero, that is v α ′ ′ = 0, thus. (13.3.3) v α = V + ω × r α ′. Consider the translational velocity of the body-fixed point O to be zero, i.e. V = 0 and let R = 0, then r α = r α ′. These assumptions allow the linear momentum of the particle ... WebFlow around a half-body is obtained by the addition of a source to a uniform flow. The flow around a half-body: (a) superposition of a source and a uniform flow; (b) replacement of streamline ψ = πbU with solid boundary to form half-body.
