QUESTION: 1

### The stress represented by sin (t) + 1 belongs to which category?

Solution:

Explanation: The minimum stress value is zero and hence is belongs to Repeated Stress category.

QUESTION: 2

### The stress represented by sin (t) + 2 belongs to which category?

Solution:

Explanation: The mean as well as the amplitude value is non zero hence it belongs to Fluctuation Stress Category.

QUESTION: 3

### The stress represented by sin (t) + 4 belongs to which category?

Solution:

Explanation: The mean as well as the amplitude value is non zero hence it belongs to Alternation Stresses category which is the other name of Fluctuation Stresses.

QUESTION: 4

The stress represented by cos (t) belongs to which category?

Solution:

Explanation: Half cycle is in tensile stress and other half in compressive stress, hence it belongs to Reversed Stresses Category.

QUESTION: 5

If the mean stress value for a sinusoidal stress function is zero, then this type of stress falls in which category?

Solution:

Explanation: If mean is to be zero, then there must be compressive as well as tensile stresses and hence belongs to reversed stresses category.
