Theory of Machine The magnitude of linear velocity of a point B on a link AB relative to point A is, (Where ω = Angular velocity of the link AB) ω × AB ω² × AB (ω × AB)² ω × (AB)² ω × AB ω² × AB (ω × AB)² ω × (AB)² ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The Kutzbach criterion for determining the number of degrees of freedom (n) is (where l = number of links, j = number of joints and h = number of higher pairs) n = 2(l - 1) - 3j - h n = 3(l - 1) - 2j - h n = 2(l - 1) - 2j - h n = 3(l - 1) - 3j - h n = 2(l - 1) - 3j - h n = 3(l - 1) - 2j - h n = 2(l - 1) - 2j - h n = 3(l - 1) - 3j - h ANSWER DOWNLOAD EXAMIANS APP
