QUESTION: 1

Belt, chain and rope are called rigid drives.

Solution:
QUESTION: 2

In flexible drives, rotary motion of driving shaft is directly converted to rotary motion of driven shafts

Solution:

Explanation: It is first converted into translator and then into rotary.

QUESTION: 3

Flexible drive can absorb shock loads and damp vibrations.

Solution:

Explanation: Intermediate link is long and flexible.

QUESTION: 4

Velocity ratio in both flexible and rigid drive is constant.

Solution:

Explanation: In flexible drive, velocity ratio is not constant.

QUESTION: 5

Is there any worry for overloading conditions in flexible belt drives?

Solution:

Explanation: In case of overloading, belt slips over the pulley and hence protect it from the overload.

QUESTION: 6

V belts have v shaped cross section.

Solution:

Explanation: They have trapezoidal cross section.

QUESTION: 7

The force of friction between belt and V grooved pulley is high.

Solution:

Explanation: Due to wedge action, force of friction is high.

QUESTION: 8

V belts result in smooth and quite operation even at high speeds.

Solution:

Explanation: V belts are endless.

Solution:

Explanation: The efficiency of flat belt drive is more that V belt drive.

QUESTION: 10

There is problem of bending stress in the V belt drive.

Solution:

Explanation: The ratio of cross sectional height to pulley diameter is high.
