Question:-
Match List-I with List-II and select the correct answer using the codes given below the lists:
List – I
A. interference
B. Dynamic load on tooth
C. Static load
D. Contact ratio
List-II
1. Arc of approach arc of recess, circular pitch .
2. Lewis equation
3. minimum number of teeth on pinion.
4. Inaccuracies in tooth profile
Option (A)


A B C D
3 4 1 2

Option (B)


A B C D
1 2 3 4

Option(C)


A B C D
4 3 2 1

Option(D)


A B C D
3 4 2 1

Correct Option:
(D)
Question Solution:
To avoid interface certain minimum number of teeth must be provided on the gear
Contact ratio = (Arc of contact/ Circular pitch)
Lewis equation gives static load on teeth
