Theory of Machine Angle of ascent of cam is defined as the angle Of rotation of the cam for a definite displacement of the follower During which the follower returns to its initial position Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Through which the cam rotates during the period in which the follower remains in highest position Of rotation of the cam for a definite displacement of the follower During which the follower returns to its initial position Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Through which the cam rotates during the period in which the follower remains in highest position 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/G G.I₂ I₂/G² G².I₂ I₂/G G.I₂ I₂/G² G².I₂ ANSWER DOWNLOAD EXAMIANS APP
