Answer:
The Poisson's ratio for the material is 0.0134.
Step-by-step explanation:
The Poisson's ratio (), no unit, is the ratio of transversal strain (
), in inches, to axial strain (
), in inches:
(1)
(2)
(3)
Where:
- Initial axial length, in inches.
- Final axial length, in inches.
- Initial transversal length, in inches.
- Final transversal length, in inches.
If we know that ,
,
and
, then the Poisson's ratio is:
The Poisson's ratio for the material is 0.0134.
Answer:
Option C
Step-by-step explanation:
Note that the relation describing the set of ordered pairs does not change at a costing rate
Therefore the relationship is not linear.
However, the exchange rate increases by a factor of 2 units when n increases 1 unit. This allows us to conclude that the relationship is quadratic
Note that the following ordered pairs belong to the function
A = {(2, 4), (3, 9), (4, 16), (5, 25)}
The set of ordered pairs that we have is:
B = {(2, 2), (3, 7), (4, 16), (5, 23)}
Note that there is a similarity between both sets of ordered pairs.
In set B the values of y are always 2 units less than the values in y of the set A.
Then we deduce that since the function that models the set A is then the function that contains the ordered pairs of the B set is:
The correct option is option C)
