A cylindrical rod of a metal alloy is stressed elastically in tension. The original diameter was 11 mm and a force of 55 kN was

applied. Compute the diameter of the rod upon loading, in millimeters, if the alloy has a modulus of elasticity is 125 GPa and a Poisson's ratio of 0.31. Answer Format: X.XXX Unit: mm

Answer:

10.984mm

Explanation:

by elastic modulus

stress=modulus of elasticity*strain

stress=loading/area                          area" cross-section"

11mm=0.011m

area=π(d/2)^2=π(0.011/2)^2=9.503*10^-5 square meter

stress=55000/(9.503*10^-5)=578.745 MPa

convert MPa and GPa to pascal.

strain=stress/modulus=(578.745*10^6)/(125*10^9)=0.00463............axial strain

v=Poisson  ratio

lateral strain=(-v)*axial strain= -0.31*0.00463

lateral strain= -1.4353*10^-3=change in diameter/ original diameter

change in diameter=(-1.4353*10^-3)*0.011= -1.57883*10^-5 m

negative indicates decrease in diameter.

decrease in dia.=0.01578mm

new diameter=11-0.01578= 10.984mm

deff fn [24]

Answer:

The classification of the concern is listed in the interpretation segment below.

Explanation:

(a)...

<u>Simple cubic lattice</u>

<u />a=2r

Now,

The unit cell volume will be:

=a^3

=(2r)^3

=8r^3

At one atom per cell, atom volume will be:

=(1)\times (\frac{4 \pi r^3}{3})

Then the ratio will be:

Ratio=\frac{\frac{4 \pi r^3}{3}}{8r^3}\times 100 \ percent

        =52.4 \ percent

(b)...

<u>Diamond lattice</u>

The body diagonal will be:

d=8r=a\sqrt{3}

       a=\frac{8}{\sqrt{3}}r

The unit cell volume will be:

=a^1

=(\frac{8r}{\sqrt{3}})^1

At eight atom per cell, the atom volume will be:

=8(\frac{4 \pi r^1}{3})

Then the Ratio will be:

Ratio=\frac{8(\frac{4 \pi r^1}{3})}{(\frac{8r}{\sqrt{3}})^1}\times 100 \ percent

        =34 \ percent

Note: percent = %

Allura Red Moles
Ivanshal [37]

Answer:

Die of intoxication by water first

Explanation:

We assume that the weight of the man is 154.35 pounds which is 70 kg

LD50 water = 90g per kg

Maximum concentration = 90x70

= 6300grams

Convert grams to liters

6300/100

= 6.3 litres

From here we get amount of kool aid

6.3 x 1.97x10^-4

= 1.24x10^-3

= 1.24grams

1.24 grams is below 420 kool aid is lower than LD50 with about 6 grams for 1 kg (6x70kg = 420). So 420 is lethal dose. But 1.24 is less than this so the man has to die of water intoxication first.

Thepotemich [5.8K]

Answer:

Explanation:

In the first instance, you had a logic function, which you had derived using some sort of a truth table, then reduced it using K-maps, and finally derived the simplified logic. If you had used logic gates to implement the logic, the result would have been the fact that there were a lot of logic gates used. For example, for a function of 2 variables, we would need 4 AND gates and 1 OR gate. Thus, the resulting circuitry would have looked very complex.

Whereas, if you would use a microcontroller to implement the logic, all you need would be a piece of code to run the logic. There would either be minimum number of gates (or no gates at all, depending on the logic you wanted to implement).

Thus the microcontroller would make the circuit look a lot less complex. Making the design and texting simpler and since there are now fewer components to test. Microcontrollers is that on the same piece of silicon, you could embed a lot more complex logic or program, than using purely digital gates this is another good that comes with Microcontrollers.
