QUESTION: 1

### Consider a simple gear train having odd number of idler gears. The direction of motion of the driven gear will

Solution:

In simple gear train having odd number of ilder gears, the direction of motion of the driven gear will be same as that of the driving gear and vice- versa.

QUESTION: 2

Solution:

QUESTION: 3

### If in a gear trains, the first wheel is a driver and the last wheel is a driven then train value is defined as the

Solution:

The reciprocal of the speed ratio (or velocity ratio) is known as train value of gear train.

QUESTION: 4

A gear train, in which atleast one of the gear axes is in motion relative to the frame, is known as

Solution:
QUESTION: 5

Solution:
QUESTION: 6

The gear train usually employed in clocks is a

Solution:
QUESTION: 7

In a simple gear train, if the number of idle gears is odd, then the motion of driven gear will

Solution:

The speed ratio and the train value, in a simple train of gears, is independent of the size and number of intermediate gears. These intermediate gears are called idle gears, as they do not affect the speed ratio or train value of the system.

QUESTION: 8

The gear train usually employed in clocks is

Solution:

In reverted gear train, first and last gear is on the same axis such an arrangement has application on speed reducers, clocks and machine tools.

QUESTION: 9

A reverted gear train is one in which the output shaft and input shaft

Solution:

If the axes of the first and the last wheel of a compound gear coincide, it is called a reverted gear train.

QUESTION: 10

Train value of a gear train is

Solution:
