Answer:

Poission Ratio = 0.2784

Step-by-step explanation:

we know that

Poission ratio is defined as

μ = $\frac{-lateral strain}{longitudinal strain}$

We also know that lateral strain = $\frac{Final width-Initial width}{Initial Width}$

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 = $\frac{2.89945-2.9}{2.9}$

Lateral strain = $-1.8965X10^{-4}$

Similarly longitudinal strain = $\frac{Final Length-Initial Length}{Initial Length}$

Thus longitudinal strain = $\frac{7.40504ft-7.4ft}{7.4ft}$

Longitudinal strain = $6.8108X10^{-4}$

Thus by formula poission ratio = $\frac{-(-1.8965X10^{-4}}{6.8108X10^{-4}}$

Poission Ratio = 0.2784

Find the solutions for a triangle with a = 16, c =12, and B = 63º.

maks197457 [2]

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)

$b = \sqrt{a^{2}+c^{2}-2\cdot a \cdot c \cdot \cos B}$

$b = \sqrt{16^{2}+12^{2}-2\cdot (16)\cdot (12) \cdot \cos 63^{\circ}}$

$b \approx 15.022$

Angle A (Law of Cosine)

$\cos A = -\frac{a^{2} - b^{2}-c^{2}}{2\cdot b \cdot c}$

$\cos A = - \frac{16^{2}-15.022^{2}-12^{2}}{2\cdot (15.022)\cdot (12)}$

$\cos A = 0.315$

$A= \cos^{-1} 0.315$

$A \approx 71.639^{\circ}$

Angle C (Sum of internal angles in triangles)

$C = 180^{\circ} - 63^{\circ} - 71.639^{\circ}$

$C = 45.361^{\circ}$

Hence, the right answer is B.

If a barrel averages 50 pounds and a crate 120 pounds, write an inequality that describes when x barrels and y crates will caus

natima [27]

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.
