Theory of Machine Kinematic pairs are those which have Point or line contact between the two elements when in motion Two elements that permit relative motion Elements of pairs not held together mechanically Surface contact between the two elements when in motion Point or line contact between the two elements when in motion Two elements that permit relative motion Elements of pairs not held together mechanically Surface contact between the two elements when in motion ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The two elements of a pair are said to form a higher pair, when they Have a surface contact when in motion Have a line or point contact when in motion Are kept in contact by the action of external forces, when in motion Permit relative motion Have a surface contact when in motion Have a line or point contact when in motion Are kept in contact by the action of external forces, when in motion Permit relative motion 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) (1/2).Iω² I ω ωP (1/2). I ω ωP Iω² (1/2).Iω² I ω ωP (1/2). I ω ωP Iω² ANSWER DOWNLOAD EXAMIANS APP
