Question

Which mechanical drive is specifically used to impart a reciprocating or oscillatory motion to another body in contact?

• A. Gear Drive
• B. Belt Drive
• C. Cam and Follower
• D. Chain Drive

Hint:

\textbf{Cam + Follower = Rotary input $\rightarrow$ Reciprocating/oscillating output}.
Used in engines and automated machinery.

Answer 1

The Correct Option is C

Concept: Different mechanical drives are used to transmit motion and power. Some are specifically designed to convert rotary motion into reciprocating or oscillatory motion.
Step 1: Understanding the requirement.
The question asks for a mechanism that imparts reciprocating or oscillatory motion to another body in contact.
Step 2: Identifying the correct mechanism.
A Cam and Follower mechanism converts rotary motion of the cam into reciprocating or oscillatory motion of the follower. The follower remains in contact with the cam surface.
Step 3: Eliminating incorrect options.

• Gear Drive transmits rotary motion between shafts.
• Belt Drive transmits motion using belts and pulleys.
• Chain Drive transmits rotary motion using chains and sprockets.

Conclusion:
Thus, the correct answer is Cam and Follower.
