Cam and Follower Mechanisms

The video tutorial introduces the cam and follower mechanism, explaining how it works and its components. It then categorizes different types of cams based on their shapes, such as radial, cylindrical, and spherical cams, detailing their unique characteristics and applications. The tutorial also covers various types of followers, including knife edge, roller, and flat faced followers, and discusses their advantages and disadvantages. The video concludes with a summary of the different types of cams and followers.

What is the primary function of a cam in a cam and follower mechanism?

• To reduce friction

• To act as a guide for the follower

• To achieve reciprocating or translating motion

• To provide rotational motion

Which type of cam is also known as a plate or disc cam?

• Cylindrical cam

• Radial cam

• Wedge cam

• Globoidal cam

What is a unique feature of a cylindrical cam?

• It is used for noiseless operation

• It has a groove cut on its surface

• It has a flat plate design

• It has a spherical shape

Which type of cam is used for noiseless operation?

• Wedge cam

• Conjugate cam

• Cylindrical cam

• Radial cam

What is a disadvantage of knife edge followers?

• They encounter more wear

• They require frequent lubrication

• They are complex to design

• They are expensive to manufacture

Which type of follower is used to minimize wear?

• Flat faced follower

• Roller follower

• Spherical faced follower

• Knife edge follower

What is the characteristic of an inline follower?

• Its axis is offset from the cam center

• It is used for quick motion

• Its axis coincides with the cam center

• It has a spherical contact surface

What defines an offset follower?

• Its axis is aligned with the cam center

• It has a flat contact surface

• Its axis is offset from the cam center

• It is used for noiseless operation

What type of motion does a translating follower have?

• Straight line motion

• Oscillating motion

• Rotational motion

• Circular motion

Which type of follower has an oscillating motion?

• Pivoted follower

• Offset follower

• Translating follower

• Inline follower
