Thank you for the wonderful painting. You are so talented! I was thrilled that you chose to paint horses. You must have remembered that I was crazy about horses when I was a little kid—and I still love them. I have hung the painting in my room so that I can see it every morning when I wake up.

Your loving niece,

Stainless steel rod has a gap of 0.0371 mm between its end and a rigid wall. The modulus of elasticity E = 210 GPa. The coeffici

alexgriva [62]

Answer:

The value of stress in the rod is 220.9 MPa

Explanation:

As the data is not complete, a similar question is found online and the missing data is used from that question. Similar question is attached herewith.

From the given data

The allowed total strain is given as $\delta_a=0.0371 mm$

The length of the rod is missing in this data which in the additional data is l=290 mm

The Modulus of Elasticity is given as E=210 GPa

The coefficient of thermal expansion is given as α= 10 ×10⁻⁶ mm / mm⋅°C.

The initial temperature is room temperature which is given as T1=22C

The final temperature is given as T2=140 C

The strain due to stress is given as

$\delta_s=\dfrac{\sigma l}{E}$

$\delta_s=\dfrac{\sigma (0.290)}{210\times 10^9}\\\delta_s=1.38095\sigma \times 10^{-12}$

Now the thermal strain is given as

$\delta_c=l\alpha \Delta T\\\delta_c=0.290\times 10 \times 10^{-6}(T_2-T_1)\\\delta_c=0.290\times 10 \times 10^{-6}(140-22)\\\delta_c=0.0003422$

So now the equation of the allowed strain is given as

$\delta_a=\delta_s+\delta_c\\0.0371\times 10^{-3}=1.38095\sigma \times 10^{-12}+0.0003422\\\dfrac{1.38095}{10^{12}}\sigma+0.0003422=\frac{0.0371}{1000}\\\sigma=-\dfrac{10^{12}\times \:0.0003051}{1.38095}\\\sigma=-220934863.68 Pa\\\sigma=-220.9 MPa$

The negative sign indicate that the stress is compressive.

The value of stress in the rod is 220.9 MPa

Illusion [34]

As

As is the subordinating conjunction. It transitions between the two main ideas in the sentence. The first main idea is the squad and speaker stretching. The second idea is the pep band playing. Subordinating conjunctions often tell you time. In this case, as tells you that the stretching is happening at the same time the band starts to play.
