Cam and Follower

What is the main purpose of a cam in mechanical design?

• To generate electrical energy
  

• To convert rotary motion into reciprocating motion

• To reduce friction in a machine

• 1. To increase speed of rotation

Which cam shape in the video produces a smooth, continuous movement?

• 1. Snail cam
     

• 1. Hex cam

• 1. Egg cam

• 1. Eccentric cam

How does the snail cam’s movement differ from other cam types?

• It creates a single lift and drop movement that works only in one direction

•  It spins continuously without moving the follower
  

• It causes rapid vibration of the follower
  

• 1. It produces multiple smooth lifts

In the tutorial, what role does the follower play in the cam mechanism?

• It rotates the cam
  

•  It follows the cam profile to create motion

• It holds the cam in place
  

• It powers the entire mechanism

Why might a designer choose an eccentric cam for a product?

• To create an uneven, unpredictable motion

• To create a smooth, simple reciprocating motion

• To make the follower vibrate rapidly

• Because it is the easiest to manufacture

What is the importance of clearance between the follower and cam housing, as explained in the video?

•  It keeps the follower stuck on the cam

• It increases the friction for better control
  

• It prevents friction that would stop the follower’s movement
  

•  It makes the follower move slower
