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 G².I₂ I₂/G² I₂/G G.I₂ G².I₂ I₂/G² I₂/G G.I₂ ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the addenda on pinion and wheel is such that the path of approach and path of recess are half of their maximum possible values, then the length of the path of contact is given by (where r = Pitch circle radius of pinion, R = Pitch circle radius of wheel, and φ = Pressure angle) [(r² + R²) sinφ]/2 [(r + R) cosφ]/2 [(r + R) sinφ]/2 [(r² + R²) cosφ]/2 [(r² + R²) sinφ]/2 [(r + R) cosφ]/2 [(r + R) sinφ]/2 [(r² + R²) cosφ]/2 ANSWER DOWNLOAD EXAMIANS APP
