Theory of Machine Cam angle is defined as the angle Of rotation of the cam for a definite displacement of the follower Through which, the cam rotates during the period in which the follower remains in the highest position 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 Of rotation of the cam for a definite displacement of the follower Through which, the cam rotates during the period in which the follower remains in the highest position 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 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The static balancing is satisfactory for low speed rotors but with increasing speeds, dynamic balancing becomes necessary. This is because, the Unbalanced couples are caused only at higher speeds Effects of unbalances are directly proportional to the speed Unbalanced forces are not dangerous at higher speeds Effects of unbalances are proportional to the square of the speed Unbalanced couples are caused only at higher speeds Effects of unbalances are directly proportional to the speed Unbalanced forces are not dangerous at higher speeds Effects of unbalances are proportional to the square of the speed ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The velocity of sliding of meshing gear teeth is(Where ω₁ and ω₂ are angular velocities of meshing gears and ‘y’ is distance between point of contact and the pitch point) (ω₁ + ω₂)/y (ω₁ × ω₂) y (ω₁/ω₂) y (ω₁ + ω₂) y (ω₁ + ω₂)/y (ω₁ × ω₂) y (ω₁/ω₂) y (ω₁ + ω₂) y ANSWER DOWNLOAD EXAMIANS APP
