## This is a more, "whats your opinion question" so answers may vary from person to person

The industrial revolution created many jobs, boosted the economy, but created many issues too. Including but not limited too, child labor, decrease in workplace saftey for the sake of profits, hard hours, and many injuries and deaths (i.e. Triangle Shirtwaist Factory Fire). In the short term, companies used the oppertunity of little workers rights to exploit them for profits, yet in the long term boomed the economy and our exports and America's indepence from buying imports.

dmitriy555 [2]

Complete Question:

A metal plate of 400 mm in length, 200mm in width and 30 mm in depth is to be machined by orthogonal cutting using a tool of width 5mm and a depth of cut of 0.5 mm. Estimate the minimum time required to reduce the depth of the plate by 20 mm if the tool moves at 400 mm per second.

Answer:

$T_{min} =$ 26 mins 40 secs

Explanation:

Reduction in depth, Δd = 20 mm

Depth of cut, $d_c = 0.5 mm$

Number of passes necessary for this reduction, $n = \frac{\triangle d}{d_c}$

n = 20/0.5

n = 40 passes

Tool width, w = 5 mm

Width of metal plate, W = 200 mm

For a reduction in the depth per pass, tool will travel W/w = 200/5 = 40 times

Speed of tool, v = 100 mm/s

$Time/pass = \frac{40*400}{400} \\Time/pass = 40 sec$

minimum time required to reduce the depth of the plate by 20 mm:

$T_{min} =$ number of passes * Time/pass

$T_{min} =$ n * Time/pass

$T_{min} =$ 40 * 40

$T_{min} =$ 1600 = 26 mins 40 secs

Natali5045456 [20]

Answer:

The work done is 3654.83 J/mol

Explanation:

The process is an isothermal process since the air temperature is kept constant during the release.

W = RT ln(P1/P2)

R is gas constant = 8.314 J/mol.K

T is air temperature = 400 K

P1 is initial pressure of air = 600 kPa

P2 is final temperature of air = 200 kPa

W = 8.314×400 ln(600/200) = 3325.6×ln 3 = 3325.6×1.099 = 3654.83 J/mol

Sergio [31]

Answer:

77.2805 μF

Explanation:

Given data :

V = 2460 V

Q = 191 Kva

<u>Calculate the size of Each capacitor </u>

first step : calculate for the value of Xc

Q = V^2/ Xc

Xc ( capacitive reactance ) = V^2 / Q = 2460^2 / ( 191 * 10^3 ) = 31.683 Ω

Given that 1 / 2πFc = 31.683

∴ C ( size of each capacitor ) = $\frac{1}{2\pi *65 *31.683}$ = 77.2805 μF
