Determine the critical crack length for a through crack contained within a thick plate of 7150-T651 aluminum alloy that is in un
Mila [183]

Explanation:

Formula to determine the critical crack is as follows.

          K_{IC} = \gamma \sigma_{f} \sqrt{\pi \times a}

  \gamma = 1,     K_{IC} = 24.1

  [/tex]\sigma_{y}[/tex] = 570

and,   \sigma_{f} = 570 \times \frac{3}{4}

                       = 427.5

Hence, we will calculate the critical crack length as follows.

      a = \frac{1}{\pi} \times (\frac{K_{IC}}{\sigma_{f}})^{2}

        = \frac{1}{3.14} \times (\frac{24.1}{427.5})^{2}

       = 10.13 \times 10^{-4}

Therefore, largest size is as follows.

            Largest size = 2a

                                 = 2 \times 10.13 \times 10^{-4}

                                 = 20.26 \times 10^{-4}

Thus, we can conclude that the critical crack length for a through crack contained within the given plate is 20.26 \times 10^{-4}.

Two guitars are playing together producing a beat frequency. The first guitar is playing at a frequency of 867 Hz and the beat i
IgorLugansk [536]

Answer:

892 Hz or 842 Hz

Explanation:

Given

The frequency of first guitar is 867 Hz

Beat is produced for every 0·04 s

∴ Beat has a time period of 0·04 s

<h3>Beat frequency is defined as the inverse of the time period of the beat </h3>

Beat frequency = 1 ÷ (Time period) = 1 ÷ 0·04 = 25 Hz

Let the frequency of the second guitar be f Hz

<h3>Beat frequency is defined as the absolute difference between the two frequencies</h3>

∴ Beat frequency = (867 - f) or (f - 867)

First case

25 = 867 - f ⇒ f = 842 Hz

Second case

25 = f - 867 ⇒ f = 892 Hz

∴ Possible frequencies of second guitar could be 892 Hz or 842 Hz
