1. : Is it possible to lower the centre distance as much as we wish?
(A) Yes power transmission increases
(B) Can’t be cited
(C) No
(D) None of these

(A) 20 m/s
(B) 25 m/s
(C) 30 m/s
(D) None of the above

3. : Velocity ratio for chain drive is lesser than that for belts.
(A) Yes
(B) Can’t be determined
(C) In some cases
(D) No

4. : Fabric rubber belts are not mostly used as they can’t work at high speeds.
(A) They can’t be used at velocities 50 m/s
(B) None of the listed
(C) Limiting velocity is 20 m/s
(D) They can be used at high velocities

5. : The layer of a belt is generally known as

(B) Layer
(C) Segment
(D) Ply

6. : Power transmitting capacity of V belts is more than that of flat belt.
(B) No
(C) Yes
(D) None of the listed

7. : Select the optimum velocity of the belt for maximum transmission is defined by √P/6m.
(A) Yes
(B) By replacing 6 by 3
(C) No
(D) None of the listed

8. : Creep is the slight absolute motion of the belt as it passes over the pulley.
(A) Yes
(B) It is absolute motion
(C) None of the listed
(D) No, it is a relative motion

9. : A shorter centre distance usually has favour in belt drives.
(A) Yes due to instability
(B) No due to stability
(C) Yes due to stability
(D) No due to instability

(A) By 3D
(B) By 5D
(C) By 4D
(D) By D
