The best step for the engineers to make next is option D. Begin to design an airplane using this metal.

<h3>What is the metallic is plane parts?</h3>

Aluminum and its alloys are nevertheless very famous uncooked substances for the production of business planes, because of their excessive electricity at exceedingly low density. Currently, excessive-electricity alloy 7075, which includes copper, magnesium and zinc, is the only used predominantly withinside the plane industry.

The solution is D, due to the fact even as it's far crucial to marketplace the fabric and ensure humans are inquisitive about buying, they first want to attempt to layout aircraft the usage of this fabric. There isn't anyt any use promoting an aircraft constituted of this material_ if a aircraft can not be built.

A 3-phase induction motor with 4 poles is connected to a voltage source with an amplitude of 209 Vrms and a frequency of 120 Hz.

Ket [755]

Answer:

<em>T = 25.41 Nm</em>

Explanation:

Calculating Nsync (Synchronous Speed):

$Nsync = 120f/P$

$Nsync = 120 x 120 / 4\\Nsync = 3600 rpm$

$Wsync = 3600 * 2\pi /180\\Wsync = 377 rad/s$

Calculating s (Slip):

$s = (Nsync - Nm) / Nsync \\[tex]s = (3600-2464)/3600\\s = 0.3156$

Calculating Vth (Thevenin Voltage):

$Vth = Vph (Xm / \sqrt{Rs^{2} + (Xs+Xm)^{2} })\\Vth = 209 (76 / \sqrt{(2.3)^{2} + (1.3 + 76)^{2} }\\Vth = 205.39 V$

Calculating Rth (Thevenin Resistance):

$Rth = Rs (Xm/Xs + Xm)^{2} \\Rth = 2.3 (76/1.3 + 76)^{2} \\Rth = 2.22 ohm$

Calculating Xth (Thevenin Reactance):

Xth = Xs = 1.3 ohm

Calculating Torque:

$T = (3Vth^{2}Rr/s) / (Wsync[(Rth+Rr/s)^{2} + (Xth + Xr)^{2}])\\T = (3*205.39*0.7/0.3156) / 377[(2.22+0.7/0.315)^{2} + (1.3+1.8)^{2}]$

T = 280699 / 377 [19.69 + 9.61]

<em>T = 25.41 Nm</em>
