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 = 3(l - 1) - 3j - h n = 2(l - 1) - 2j - h n = 2(l - 1) - 3j - h n = 3(l - 1) - 2j - h n = 3(l - 1) - 3j - h n = 2(l - 1) - 2j - h ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A Hartnell governor has its controlling force (Fc) given by Fc = ar + b, where r is the radius of rotation and a and b are constants. The governor becomes isochronous when a is +ve and b = 0 a is +ve and b is also +ve a is +ve and b is -ve a = 0 and b is +ve a is +ve and b = 0 a is +ve and b is also +ve a is +ve and b is -ve a = 0 and b is +ve ANSWER DOWNLOAD EXAMIANS APP
