Answer:
The stress S = 1935 [Psi]
Explanation:
This kind of problem belongs to the mechanical of materials field in the branch of the mechanical engineering.
The initial data:
P = internal pressure [Psi] = 90 [Psi]
Di= internal diameter [in] = 22 [in]
t = wall thickness [in] = 0.25 [in]
S = stress = [Psi]
Therefore
ri = internal radius = (Di)/2 - t = (22/2) - 0.25 = 10.75 [in]
And using the expression to find the stress:
![S=\frac{P*D_{i} }{2*t} \\replacing:\\S=\frac{90*10.75 }{2*0.25} \\S=1935[Psi]](https://tex.z-dn.net/?f=S%3D%5Cfrac%7BP%2AD_%7Bi%7D%20%7D%7B2%2At%7D%20%5C%5Creplacing%3A%5C%5CS%3D%5Cfrac%7B90%2A10.75%20%7D%7B2%2A0.25%7D%20%5C%5CS%3D1935%5BPsi%5D)
In the attached image we can see the stress σ1 & σ2 = S acting over the point A.
Answer:
i think its the golgi body tbh
Explanation:
hope this helps
Answer:
A. Rocket A will travel farther horizontally than rocket B.
Explanation:
This is because from the x axis, 40 m/s at 90 degrees travels directly vertical. 40 m/s at 70 degrees is slightly horizontal, so it will travel further horizontally.
Answer:
No they are not the same.
Explanation:
S=d/t Speed equals distance divided by time. Leah's wave took 10 seconds, and the distance was 6 meters.
6/10=.6
Betty's wave took 10 seconds, but the distance was 60 meters this time.
60/10=6
We know that 6 and .6 are not the same numbers, so we can see that the waves aren't the same.
I hope this helps!!
