Answer:
B.
Explanation:
A safety-critical system (SCS) or life-critical system is a system whose failure or malfunction may result in one (or more) of the following outcomes: death or serious injury to people. loss or severe damage to equipment/property.
Answer:
q=39.15 W/m²
Explanation:
We know that
Thermal resistance due to conductivity given as
R=L/KA
Thermal resistance due to heat transfer coefficient given as
R=1/hA
Total thermal resistance
![R_{th}=\dfrac{L_A}{AK_A}+\dfrac{L_B}{AK_B}+\dfrac{1}{Ah_1}+\dfrac{1}{Ah_2}+\dfrac{1}{Ah_3}](https://tex.z-dn.net/?f=R_%7Bth%7D%3D%5Cdfrac%7BL_A%7D%7BAK_A%7D%2B%5Cdfrac%7BL_B%7D%7BAK_B%7D%2B%5Cdfrac%7B1%7D%7BAh_1%7D%2B%5Cdfrac%7B1%7D%7BAh_2%7D%2B%5Cdfrac%7B1%7D%7BAh_3%7D)
Now by putting the values
![R_{th}=\dfrac{0.01}{0.1A}+\dfrac{0.02}{0.04A}+\dfrac{1}{10A}+\dfrac{1}{20A}+\dfrac{1}{0.3A}](https://tex.z-dn.net/?f=R_%7Bth%7D%3D%5Cdfrac%7B0.01%7D%7B0.1A%7D%2B%5Cdfrac%7B0.02%7D%7B0.04A%7D%2B%5Cdfrac%7B1%7D%7B10A%7D%2B%5Cdfrac%7B1%7D%7B20A%7D%2B%5Cdfrac%7B1%7D%7B0.3A%7D)
![R_{th}=4.083/A\ K/W](https://tex.z-dn.net/?f=R_%7Bth%7D%3D4.083%2FA%5C%20K%2FW)
We know that
Q=ΔT/R
![Q=\dfrac{\Delta T}{R_{th}}](https://tex.z-dn.net/?f=Q%3D%5Cdfrac%7B%5CDelta%20T%7D%7BR_%7Bth%7D%7D)
![Q=A\times \dfrac{200-40}{4.086}](https://tex.z-dn.net/?f=Q%3DA%5Ctimes%20%5Cdfrac%7B200-40%7D%7B4.086%7D)
So heat transfer per unit volume is 39.15 W/m²
q=39.15 W/m²
Answer:
A. Identify the need, recognize limitations of current toothpaste containers, and then brainstorm ideas on how to improve the existing
Explanation:
To design an improved toothpaste container, we must identify the needs of the customer, one of the major need is to make the container attractive to the sight. This is the first thing that will prompt a customer to wanting to buy the product (The reflectance/appearance).
Then recognize the limitation of the current design, what needed change. This will help in determining what is needed to be included and what should be removed based on identified customers need.
The last step is to brainstorm ideas on how to improve the existing designs. Get ideas from other colleagues because there is a saying that two heads are better than one. This will help in coming to a reasonable conclusion on the new design after taking careful consideration of people's opinion.
Answer:
62990.08 N/M
Explanation:
Circumferential stress, or hoop stress, a normal stress in the tangential (azimuth) direction. axial stress, a normal stress parallel to the axis of cylindrical symmetry. radial stress, a stress in directions coplanar with but perpendicular to the symmetry axis.

Answer:
The Euler buckling load of a 160-cm-long column will be 1.33 times the Euler buckling load of an equivalent 120-cm-long column.
Explanation:
160 - 120 = 40
120 = 100
40 = X
40 x 100 / 120 = X
4000 / 120 = X
33.333 = X
120 = 100
160 = X
160 x 100 /120 = X
16000 / 120 = X
133.333 = X
