Theory of Machine The two parallel and coplanar shafts are connected by gears having teeth parallel to the axis of the shaft. This arrangement is known as Bevel gearing Spur gearing Helical gearing Spiral gearing Bevel gearing Spur gearing Helical gearing Spiral gearing 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 G².I₂ I₂/G G.I₂ I₂/G² G².I₂ I₂/G G.I₂ ANSWER DOWNLOAD EXAMIANS APP
