Answer: which is Choice B
This is the same as writing
The second "2" is not under or inside the square root.
==========================================================
Explanation:
Refer to the unit circle below. I've highlighted the angle 45 degrees and its corresponding sine value. It's the y coordinate of the point on the unit circle, for this particular angle.
Therefore,
--------------
You could alternatively draw out a 45-45-90 triangle. Let x be the leg length and the hypotenuse is 1 unit long. Solve for x and you should get
as the length of each leg.
Then take the ratio of the opposite over hypotenuse to find the same answer mentioned above.
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.
