Theory of Machine Relationship between the number of links (L) and number of pairs (P) is P = 2L + 2 P = 2L + 4 P = 2L - 4 P = 2L - 2 P = 2L + 2 P = 2L + 4 P = 2L - 4 P = 2L - 2 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A torsional system with discs of moment of inertia I₁ and I₂ as shown in the below figure, is gear driven such that the ratio of speed of shaft B to shaft A is 'G'. Neglecting the inertia of gears, the equivalent inertia of disc on shaft B at the speed of shaft A is equal to I₂/G² G.I₂ G².I₂ I₂/G I₂/G² G.I₂ G².I₂ I₂/G ANSWER DOWNLOAD EXAMIANS APP
