This set of Machine Dynamics Multiple Choice Questions & Answers (MCQs) focuses on “Partial Balancing of Locomotives”.
1. What is the total no. of cylinders in a locomotive having crank at right angles?
a) 1
b) 2
c) 3
d) 4
View Answer
Explanation: The locomotives, usually, have two cylinders with cranks placed at right angles to each other, this is done in order to have uniformity in turning moment diagram.
2. For a two cylinder locomotives, the crank are placed at right angles to each other.
a) True
b) False
View Answer
Explanation: The locatives in general have two cylinders having cranks at an angle of 90 degrees to each other in order to have uniform turning moment diagram.
3. In an inside cylinder locomotive, the position of the driving wheels is _________
a) Outside cylinder
b) Inside cylinder
c) Down to cylinder
d) Above the cylinder
View Answer
Explanation: In an inside cylinder locomotive, the two cylinders are placed in between the two driving wheels at an angle of 90 degrees to each other.
4. In an outside cylinder locomotive, the position of the driving wheels is _________
a) Outside cylinder
b) Inside cylinder
c) Down to cylinder
d) Above the cylinder
View Answer
Explanation: In an outside cylinder locomotive, the two cylinders are placed outside the two driving wheels at an angle of 90 degrees to each other.
5. A single or uncoupled locomotive is one, in which the effort is transmitted to _____
a) Both the pair of wheels
b) Alternatively between the wheels
c) One pair of wheels
d) Neither of the wheels
View Answer
Explanation: A single or uncoupled locomotive is one, in which the effort is transmitted to one pair of the wheels only.
6. In coupled locomotives, the driving wheels are connected to the leading and trailing wheel by an _______ coupling rod.
a) Inside
b) Outside
c) Sideway
d) Bottom
View Answer
Explanation: In coupled locomotives, the driving wheels are connected to the leading and trailing wheel by an outside coupling rod.
7. Identify the type of locomotive from the given figure.
a) Inside cylinder
b) Outside cylinder
c) Top cylinder
d) Bottom cylinder
View Answer
Explanation: The given figure is of an inside cylinder locomotive, In an inside cylinder locomotive, the two cylinders are placed in between the two driving wheels at an angle of 90 degrees to each other.
8. In the given figure, the locomotive is a 4 cylinder locomotive.
a) True
b) False
View Answer
Explanation: The given figure is of an inside cylinder locomotive, since there are only two cranks at right angles to each other, it is two cylinder locomotive.
9. Identify the type of locomotive from the given figure.
a) Inside cylinder
b) Outside cylinder
c) Top cylinder
d) Bottom cylinder
View Answer
Explanation: The given figure is of an outside cylinder locomotive, In an outside cylinder locomotive, the two cylinders are on the either side of the two driving wheels at an angle of 90 degrees to each other.
