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:
Step-by-step explanation:
Well if you want the answers there are 3 different ways
x = 12/5
or
x = 2.4
The answer is x=3
So c is 3
Answer:
(123-55) / 8.5
I think that should be correct.
Step-by-step explanation:
Step-by-step explanation:
Firstly, we have to find m∠J.
Since all the angles of a Δ equal 180°, angles J, L, and K should have a sum of 180°.
So,
m∠J + m∠L + m∠K = 180°
The diagram shows us that ∠L = 49° and ∠K = 90°, so we plug in those numbers in the equation.
m∠J + 49° + 90° = 180°
Then we simplify
m∠J + 139° = 180°
Subtract 139° to both sides
∠J = 41
Now the other angles.
Since ΔJKL ~ ΔRST, then ∠J ≅ ∠R, ∠K ≅ ∠S, and ∠L ≅ ∠T
Meaning, m∠J = m∠R, m∠K = m∠S, and m∠L = m∠T
Since we know m∠J = 41°, m∠K = 90°, and m∠L = 49° we could plug those in so...
41° = m∠R , 90° = m∠S , and 49° = m∠T
