Answer: Protocol model and reference model

Explanation:

There are basically two types of basic network administrator model in the network that is:

Protocol model:

This model is basically represent the 4 layer of the TCP/IP model as it describe the different functionality with the networking data which occur in the each layer of the protocol in the TCP/IP model.

Reference model:

The reference model basically provide the common reference and maintain the consistency in all the different types of the network protocol. The main purpose of this model is that it understand the different functionality of the OSI model and then used in different networking design.

Answer:

The answer is " $\bold{87.3906 \ MPa \sqrt{m}}$ ".

Explanation:

Given value:

$\sigma = 1400 \ MPa \ \ \ \ \ \ \ \ where \ \sigma = failure \ strength\\\\a = 1 \ mm = 1 \times 10^{-3} \ m \ \ \ \ \ \ \ \ \ \ where\ a = crack\ length\\\\b= 12.5 \ cm = 125 \ mm = 0.125 \ m\\\\$

$\to \alpha = \frac{a}{b} =\frac{1}{125} = 8 \times 10^{-3}\\\\$

$k_{b} = \frac{1.12 + \alpha (2.62 \alpha -1.59)}{1-0.7 \alpha}\\$

$= \frac{1.12 + (8\times 10^{-3}(2.62(8\times 10^{-3}) -1.59))}{1-(0.7 \times 8\times 10^{-3})}\\\\= \frac{1.12 + (8\times 10^{-3}(0.02096 -1.59))}{1-(0.7 \times 8\times 10^{-3})}\\\\= \frac{1.12 + (8\times 10^{-3}(-1.56904))}{1-(0.0056)}\\\\= \frac{1.12 + (-0.01255232)}{0.9944}\\\\= \frac{-1.10744768}{0.9944}\\\\= -1.11368431\\\\$

$k_{ic} = \sigma \sqrt{\pi a} \ y_b$

$=1400 \times \sqrt{\pi \times 1 \times 10^{-3} } \times -1.11368431\\\\=1400 \times 0.00177200451 \times -1.11368431\\\\=87.3906 \ MPa \sqrt{m}$

What is clearance? What is backlash? What is interference? Explain briefly.

Anton [14]

Explanation:

Clearance:

For easy matching and dis matching of hole and shaft we use size of hole little bit more than the size of shaft and this difference in size is called clearance.

Backlash:

It is the clearance between the two mating gear to avoids failure of gears.Actually when temperature of gears increases then at the same time the size of gear also increases ,due this there is a possibility foe jamming of gears so to avoids this backlash is provides.

Interference:

When two gears are matting then addendum of one gear inters into the deddendum of another gear and due to this gears get jam .This phenomenon is called interference.

a steal bar with 1 in diameter has been subjected to a tensile force of 3 tons find tensile stress in the bar

Marysya12 [62]

Answer:

stress = 8,556 Psi. or (stress = 59 Mpa)

Explanation:

stress = force / area

force P = 3 tons (convert to lbs. for units consistency)

1 ton = 2240 lbs.

P = 6,720 lbs.

steel bar Diameter D = 1 in. (convert to d

Area of steel bar = (π * 1²) / 4 = 0.785 in²

therefore, stress = 6720 lbs. / 0.785 in²

stress = 8,556 Psi.

in Mpa ----- 8556 Psi * 0.00689476 MPa/Psi = 59 Mpa
