Cam and Follower Mechanisms

The video tutorial explains the cam and follower mechanism, a mechanical device used to achieve reciprocating or oscillating motion. It covers the basic components: cam, follower, and guide. The tutorial details various types of cams, such as radial, cylindrical, wedge, conjugate, globoidal, and spherical cams, and their applications. It also classifies followers based on shape, position, and motion, including knife edge, roller, flat faced, and spherical followers. The video concludes with a call for support to create more educational content.

What type of contact is present between the cam and follower in a higher pair?

• Full contact

• Surface contact

• No contact

• Point or line contact

Which part of the cam and follower mechanism acts as the driving member?

• Guide

• Cam

• Follower

• Frame

What is the shape of a radial cam?

• Sphere

• Wedge

• Flat plate or disc

• Cylinder

In a cylindrical cam, the direction of motion of the follower is:

• Random

• Circular around the cam

• Parallel to the axis of the cam

• Perpendicular to the axis of the cam

Which type of cam provides a noiseless operation due to its roller arrangement?

• Radial cam

• Cylindrical cam

• Conjugate cam

• Wedge cam

What is a key disadvantage of knife edge followers?

• Expensive to manufacture

• Noisy operation

• Complex design

• High friction and wear

Which type of follower is designed to reduce wear and tension?

• Roller follower

• Flat faced follower

• Knife edge follower

• Spherical faced follower

If the axis of the follower coincides with the center point of the cam, it is called:

• Inline follower

• Offset follower

• Oscillating follower

• Translating follower

What type of motion does a translating follower exhibit?

• Circular motion

• Straight line motion

• Oscillating motion

• Random motion
