Question 4: Attempt any THREE of the following: a) State the different ‘Follower Motions’. Draw a sketch of any one follower motion (Displacement diagrams). A follower in a cam mechanism can move in several ways depending on the cam profile. The most common types of follower motions are: 1. Uniform Velocity:The follower moves at a constant speed throughout its stroke. 2. Simple Harmonic Motion (SHM): A smooth motion used for moderate speeds, following a semi-circular path in its displacement diagram. 3. Uniform Acceleration and Retardation (UARM): The follower starts slowly, speeds up to the midpoint, and then slows down. 4. Cycloidal Motion: The smoothest motion, ideal for high-speed operations as it reduces jerk and noise. b) Differentiate between belt drive and chain drive (Any four points). c) Define the following terms related to Spur Gear: 1. Addendum: The radial distance from the pitch circle to the top of the gear tooth. 2. Dedendum: Th...
