For some transformation having kinetics that obey the Avrami equation (Equation 10.17), the parameter n is known to have a value

OleMash [197]

Answer:

t = 25.10 sec

Explanation:

we know that Avrami equation

$Y = 1 - e^{-kt^n}$

here Y is percentage of completion of reaction = 50%

t is duration of reaction = 146 sec

so,

$0.50 = 1 - e^{-k^146^2.1}$

$0.50 = e^{-k306.6}$

taking natural log on both side

ln(0.5) = -k(306.6)

$k = 2.26\times 10^{-3}$

for 86 % completion

$0.86 = 1 - e^{-2.26\times 10^{-3} \times t^{2.1}}$

$e^{-2.26\times 10^{-3} \times t^{2.1}} = 0.14$

$-2.26\times 10^{-3} \times t^{2.1} = ln(0.14)$

$t^{2.1} = 869.96$

t = 25.10 sec

You are given a body with no body forces and told that the stress state is given as: ⎡ ⎣ 3αx 5βx2 + αy γz3 5βx2 + αy βx2 0 γz3 0

Lady bird [3.3K]

Answer:

This doesn't represent an equilibrium state of stress

Explanation:

∝ = 1 , β = 1 , y = 1

x = 0 , y = 0 , z = 0 ( body forces given as 0 )

Attached is the detailed solution is and also the conditions for equilibrium

for a stress state to be equilibrium all three conditions has to meet the equilibrum condition as explained in the attached solution

An open tank in a petroleum company lab contains a layer of oil on top of a layer of water. The water height is 5 times the oil

maks197457 [2]

Answer:

Explanation:

Given

specific gravity of oil=0.79

height of oil column is h

height of water column is 5h

Gauge pressure at bottom is equivalent to $26.9\ mm$

$P_{gauge}=\rho_{Hg} gh_{Hg}$

$P_{gauge}=13.6\times 10^3\times 9.8\times 26.9\times 10^{-3}\ Pa$

Pressure due to oil and water at bottom

$P=\rho _{oil}hg+\rho _{w}5hg$

$P=0.79\rho _whg+5\rho _whg=5.79\rho _{w}hg$

$P_{gauge}=P$

$13.6\times 10^3\times 9.8\times 26.9\times 10^{-3}=5.79\times 10^3\times 9.8\times h$

$h=63.18\ mm$

To use the shear formula, the internal shear force must be:

nasty-shy [4]

Answer:

vertical, and directed along an axis of symmetry of the cross-section

Explanation:

Shear is a force in an object is in the form of stress or strain. Shear strain is the ratio of length of deformation (extension) to the perpendicular length in the plane of the force applied. Shear stress, which is the stress that tends to shear a material, is the ratio of shear force applied on a surface to the area of the surface.

The shear formula can be used to determine the maximum shear in an object and is given by; τ = $\frac{VQ}{It}$ . It is applicable when the internal shear force is vertical and directed along an axis of symmetry of the cross-section.
