Mechanics of Textile Machinery (MCQ : MODULE 6-
** ** ** Gear Trains ** )

**Question 1:
A simple gear train has four gears (termed as 1, 2, 3 & 4 from input to output). The numbers of teeth on the gears in that order z1, z2, z3 & z 4 are 20, 30, 40 & 50 respectively. The ratio of angular speed of output to input gears is**

**Question 2: A compound gear train shown in Fig. 5.3 has four gears (termed as 1, 2, 3 & 4 from input to output). The numbers of teeth on the gears in that order z1, z2, z3 & z 4 are 20, 30, 40 & 50 respectively. The ratio of angular speed of output to input gears is**

**Question 3: A gear train having the input and output gears mounted on the same axis is called **

**Question 4: The output of an epicyclic gear train used in roving machine is proportional to**

**Question 5: The inputs to the epicyclic gear train used in roving machine are**

**Question 6: Nips per minute of a comber is x and the length of fibre fringe moved during fast forward, fast backward and slow forward movement of fringe per nip are a, b and c respectively. When the nips per minute is doubled, what will be the delivery rate of fringe per nip**

**Question 7: When the nips per minute of a comber is 480, then the duration of time (in seconds) for backward movement of fibre fringe is**
