QUESTION: 1

The cam follower used in automobile engines is

Solution:
QUESTION: 2

The cam follower used in aircraft engies is a

Solution:

Automobile engines generally used spherical faced follower, whereas roller followers are used in aircraft engines. Surface stresses are minimum in mushroom follower with spherical face.

QUESTION: 3

In a radial cam, the follower moves in a direction

Solution:

Follower reciprocates in a direction perpendicular to the cam axis in radial cam while follower reciprocates in a direction parallel to-the cam axis.

QUESTION: 4

The reference point on the follower to lay the cam profile is known as the

Solution:
QUESTION: 5

Cam and follower mechanism constitutes a kinematic pair of the type

Solution:

Cam and follower have line or point contact, so it is higher pair. It is closed when retainer spring is used, usually it is of open type.

QUESTION: 6

Surface stresses are minimum in a cam follower arrangement with

Solution:
QUESTION: 7

Select the WRONG statement:

Solution:

When the follower translates along the axis perpendicular to the cam axis of rotation, it is known as flat faced or mushroom follower.

QUESTION: 8

The prime circle of a cam is

Solution:
QUESTION: 9

The cam size depends upon

Solution:

The base circle is the smallest circle (with its center at the cam center) that can be drawn tangential to the cam profile. The base circle decides the overall size of a cam and is, therefore, a fundamental feature of the cam.

QUESTION: 10

Cam followers are generally classified according to
1. the nature of its motion
2. the nature of its surface in contact with the cam
3. the speed of the cam

Which of the above statements are correct?

Solution:

Cams are classified according to
1. shape
2. follower movement, and
3. manner of constraint of the follower
