Answer:
Poission Ratio = 0.2784
Step-by-step explanation:
we know that
Poission ratio is defined as
μ = 
We also know that lateral strain =
In our case
Final width = 2.89945 in
Initial width = 2.9 in (Area of cross section (width x depth) = 2.9 in x 2.9 in)
Thus lateral strain = 
Lateral strain = 
Similarly longitudinal strain = 
Thus longitudinal strain = 
Longitudinal strain = 
Thus by formula poission ratio = 
Poission Ratio = 0.2784
Answer:
b. A = 71.6°; C = 45.40°; b =15.0
Step-by-step explanation:
The missing values can be found with the help of the Law of Cosine and properties of triangles:
Side b (Law of Cosine)



Angle A (Law of Cosine)





Angle C (Sum of internal angles in triangles)


Hence, the right answer is B.
Answer:
no they should not work togthr
We are given: Barrel quantity averages = 50 pounds.
Crate quantity = 120 pounds.
Number of barrels is taken by variable x and
Number of crates is taken by variable y.
The elevator load should be greater than of total load.
Therefore,
50 * number of barrels + 120 * number of crates > Total load.
50*x +120*y > Total load.
50x +120y > total load.
