Answer:
- <em>Cardinality of B ≤ cardinality of A</em>
Explanation:
The <em>domain</em> is the set of input elements of the function.
The <em>codomain</em> is the set of output elements of the function.
<em>Cardinality</em> is the number of elements of a set.
As per the definition of function one input cannot have more than one output. Thus, every element of the domain is related to one element of the codomain and no more.
An <em>onto function</em>, also knwon as surjection, is one in which any element of the codomain is related with at least one element of the domain. But it could happen that the same element of the domain is related with several elements of the domain. Hence, the number of elements in the codomain may be less than or equal to the number of elements of the domain, but never greater.
<h2>Conclusion:</h2>
The cardinality of B is less than or equal to the cardinality of A. Using the symbol # for cardinality that is: #B ≤ #A.
Answer:
When determining the principal stresses acting on the inclined plane AB, in hibbeler statics and mechanics solutions, verifying the maximum slideshare stress in plane shear strain and average normal strain is made using Mohr's circle method developed at point A.
Explanation:
Christian Otto Mohr designed the Mohr's circle for mechanical engineering, which is a two-dimensional plot graphical representation of the transformation law for the rubbered stress tensor, maximum shear stresses and it is useful in calculations to determine graphically the normal and shear stressess acting related by inclined planes at a point in a stressed element.

The three types of resistance that are often encountered by students studying in the university are the following:
- fear of change -- it is because they were too comfortable with what they used to have that having change may lead them into worrying or to cause stress as it is a new environment for them.
- hardships and trials -- it is a new stepping stone and they are likely to face more difficulty compared when they were still on high school.
- social relationships -- having to form a new life is one way we could say when you enter in a university and having to meet other people will be one of the factors that makes an individual stressed out.
