Theory of Machine The condition for correct steering of a Davis steering gear is (where α = Angle of inclination of the links to the vertical) cosα = c/b tanα = c/2b sinα = b/c cotα = c/2b cosα = c/b tanα = c/2b sinα = b/c cotα = c/2b ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A disc is a spinning with an angular velocity ω rad/s about the axis of spin. The couple applied to the disc causing precession will be (where I = Mass moment of inertia of the disc, and ωP = Angular velocity of precession of the axis of spin) Iω² (1/2).Iω² I ω ωP (1/2). I ω ωP Iω² (1/2).Iω² I ω ωP (1/2). I ω ωP ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The sense of Coriolis component 2 ωv is same as that of the relative velocity vector v rotated at 180° in the direction opposite to the rotation of the link containing the path 45° in the direction opposite to the rotation of the link containing the path 90° in the direction of rotation of the link containing the path 45° in the direction of rotation of the link containing the path 180° in the direction opposite to the rotation of the link containing the path 45° in the direction opposite to the rotation of the link containing the path 90° in the direction of rotation of the link containing the path 45° in the direction of rotation of the link containing the path ANSWER DOWNLOAD EXAMIANS APP
