The size of a cam depends upon
base circle
pitch circle
prime circle
pitch curve
The cam follower generally used in automobile engines is
knife edge follower
flat faced follower
spherical faced follower
roller follower
In a radial cam, the follower moves
in a direction perpendicular to the cam axis
in a direction parallel to the cam axis
in any direction irrespective of the cam axis
along the cam axis
A radial follower is one
that reciprocates in the guides
that oscillates
in which the follower translates along an axis passing through the cam centre of rotation.
none of the mentioned
Offset is provided to a cam follower mechanism to
minimise the side thrust
accelerate
avoid jerk
none of the mentioned
For low and moderate speed engines, the cam follower should move with
uniform velocity
uniform acceleration and retardation
simple harmonic motion
None
For high speed engines, the cam follower should move with
uniform velocity
simple harmonic motion
uniform acceleration and retardation
cycloidal motion
Which of the following displacement diagrams should be chosen for better dynamic performance of a cam-follower mechanism ?
simple hormonic motion
parabolic motion
cycloidal motion
none
Angle of ascent of cam is defined as the angle
during which the follower returns to its initial 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 highest position
moved by the cam from the instant the follower begins to rise, till it reaches its highest position
Angle of action of cam 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
moved by the cam from the instant the follower begins to rise, till it reaches its highest position
moved by the cam from beginning of ascent to the termination of descent
