Question

Match List I with List II:

LIST I  Mechanical Drive	LIST II  Function
A. Cams	I. Lock a mechanism when it is holding a load.
B. Gears	II. Movement of one part relative to another with minimum friction and maximum accuracy.
C. Ratchets	III. Imparts a reciprocating or oscillatory motion to another body in contact.
D. Bearings	IV. Transmission of rotary motion between parallel and inclined shafts.

Choose the correct answer from the options given below:

• A. (A)- (II), (B)- (III), (C)- (IV), (D)- (I)
• B. (A)- (II), (B)- (III), (C)- (I), (D)- (IV)
• C. (A)- (I), (B)- (II), (C)- (IV), (D)- (III)
• D. (A)- (III), (B)- (IV), (C)- (I), (D)- (II)

Hint:

Cams gears ratchets and bearings are basic mechanical components each serving specific functions in machines to provide motion control accuracy and locking

Answer 1

The Correct Option is B

- Cams (A) are used for imparting reciprocating or oscillatory motion to another body, hence (III).
- Gears (B) help in the movement of one part relative to another with accuracy, hence (II).
- Ratchets (C) are used to lock a mechanism, hence (I).
- Bearings (D) are used for transmitting rotary motion between parallel and inclined shafts, hence (IV).
