Theory of Machine A disturbing mass m₁ attached to the rotating shaft may be balanced by a single mass m₂ attached in the same plane of rotation as that of m₁, such that (where r₁ and r₂ are the radii of rotation of m₁ and m₂ respectively) m₁ m₂ = r₁ r₂ m₁ r₁ = m₂ r₂ None of these m₁ r₂ = m₂ r₁ m₁ m₂ = r₁ r₂ m₁ r₁ = m₂ r₂ None of these m₁ r₂ = m₂ r₁ 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
