You test a diode with an ohmmeter. The two readings indicate a very low value of resistance. The diode is probably __________.

Answer:

  shorted

Explanation:

A diode is a device that passes current much better in one direction than in the reverse direction.

<h3>Ohmmeter test</h3>

Conceptually, an ohmmeter applies a voltage to the device under test and reports the current through the device on a scale calibrated in ohms. It typically has a low enough open-circuit voltage, and a high enough internal resistance so as to avoid damage to parts under test.

A "continuity" tester may have an open-circuit voltage of a few tens of millivolts and/or a short-circuit current of a few microamps, so as to properly detect continuity and avoid contact damage in "dry" circuits. Such a tester is virtually useless for diode testing.

An ohmmeter suitable for diode testing will generally have an open-circuit voltage of a few volts, and a short-circuit current of a few milliamps. When such a meter is used to test a diode, it will indicate a few kilohms (or less) in the "forward" direction, and several 10s or 100s of megohms in the reverse direction.

<h3>Low-resistance readings</h3>

If the "forward" resistance reading is unusually low (a few ohms), the diode may be <em>damaged</em>. If both forward and reverse readings are unusually low, the diode my be considered to be <em>shorted</em>.

Calculate the LER for the rectangular wing from the previous question if the weight of the glider is 0.0500 Newton’s.
lapo4ka [179]

Answer:

0.2

Explanation:

Since the span and chord of the rectangular wing is missing, due to it being from the other question, permit me to improvise, or assume them. While you go ahead and substitute the ones from your question to it, as it's both basically the same method.

Let the span of the rectangular wing be 0.225 m

Let the chord of the rectangular wing be 0.045 m.

Then, the area of any rectangular chord is

A = chord * span

A = 0.045 * 0.225

A = 0.010 m²

And using the weight of the glider given to us from the question, we can find the LER for the wing.

LER = Area / weight.

LER = 0.010 / 0.05

LER = 0.2.

Therefore, using the values of the rectangular wing I adopted, and the weight of the glider given, we can see that the LER of the glider is 0.2

A company specification calls for a steel component to have a minimum tensile strength of 1240 MPa. Tension tests are conducted
polet [3.4K]

Answer:

HV = 372.4 KGf/mm^2

HR_C = 39.445

Explanation:

given data:

minimum tensile strength = 1240 MPa

we knwo that \sigma_{vrs}  and brinell hardness number (HB} relation given as

\sigma_{vrs} = 3.4 \times H.B

H.B = \frac{1240}{3.4} = 364.7

1) relation betwen H.B and Rockwell is

 HR_C = 6.96 + 0.089 HB

 HR_C = 6.96 + (0.089\times 365} = 39.445

2) relation between HB  and Vickers hardnes HV is given as

 HB \times 1.05 = HV + 10.5

HV = HB\times 1.05 - 10.5

HV = 372.4 KGf/mm^2

Alexandra [31]

Answer:

  1. Scenario
  2. Use case
  3. Scenarios
  4. Scenarios
  5. Use case

Explanation:

A <u>scenario</u> is an actual sequence of interactions (i.e., an instance) describing one specific situation; a <u>use case</u> is a general sequence of interactions (i.e., a class) describing all possible <u>scenarios</u> associated with a situation. <u>Scenarios</u> are used as examples and for clarifying details with the client. <u>Use cases</u> are used as complete descriptions to specify a user task or a set of related system features.

A brittle material typically exhibits substantial plastic deformation with high energy absorption before fracture.a) trueb) fals
tino4ka555 [31]

Answer:

<h2>The answer is FALSE</h2>

Explanation:

Brittle material are materials that don not undergo plastic deformation, they have very low plasticity that is while cracks can form without plastic deformation

The major/ common examples are glass, ceramics, graphite

In other words brittle materials break instead of bending, they have very low energy absorption as they don not undergo plastic deformation
