QUESTION: 1

### The helix angle is very small about 2⁰. The spring is open coiled spring.

Solution:

Explanation: When the helix angle is small, the plane containing each coil is almost at right angles and hence it is called closed coiled spring.

QUESTION: 2

### Which of the following function can the spring perform?

Solution:

Explanation: Spring can easily perform all the listed functions.

QUESTION: 3

### The longest leaf in a leaf spring is called centre leaf.

Solution:

Explanation: It is called master leaf.

QUESTION: 4

Multi leaf springs are not recommended for automobile and rail road suspensions.

Solution:

Explanation: They are highly used in automobile and rail road suspensions.

QUESTION: 5

The helical spring ad wire of helical torsion spring, both are subjected to torsional shear stresses.

Solution:

Explanation: The wire of helical torsion sprig is subjected to bending stresses.

QUESTION: 6

If spring index=2.5, what can be concluded about stresses in the wire?

Solution:

Explanation: If indexis <3 then stresses are high due to curvature effect.

QUESTION: 7

The spring index is the ratio of wire diameter to mean coil diameter.

Solution:

Explanation: It is the ratio of mean coil diameter to wire diameter.

QUESTION: 8

A spring with index=15 is prone to buckling.

Solution:

Explanation: Due to large variation, such a spring is prone to buckling.
