Theory of machine part -1
Question:-
Option (A)
Dynamically balanced
Option (B)
Statically balanced
Option (C)
Statically and dynamically balance
Option (D)
Not balance
Correct Option:
B
Question:-
Option (A)
The two links shown a kinematic pair.
Option (B)
The pair is completely constrained
Option (C)
The pair has incomplete constraint
Option (D)
The pair is successfully constrained
Correct Option:
C
Question Solution:
When two elements or links are connected in such a way that their relative motion is constrained they form a kinematic pair. The relative motion of a kinematic pair may be completely, incompletely or successfully constrained
Question:-
Option (A)
Both A and R are individually true and R is the correct explanation of A
Option (B)
Both A and R are true but R is not the correct explanation A
Option (C)
A is true but R is false
Option (D)
A is false but R is true
Correct Option:
A
Question Solution:
Elements of higher pair like following in cam is under the action of gravity or spring force
Question:-
Option (A)
2 and 4 are correct
Option (B)
1 and 2 are correct
Option (C)
1 and 3 are correct
Option (D)
2 and 3 are correct
Correct Option:
A
Question Solution:
FcorP/Q = 2w. `Vp/q
2 and 4 are wrong according to above equation. These should be as show below


Question:-
Option (A)
F = ar –b
Option (B)
F = ar + b
Option (C)
F = ar
Option (D)
F = a/r + b
Correct Option:
A
Question Solution:
F = ar + b ® unstable governor
F = ar ® isochronous governor
F = ar – b ® stable governor
