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.
The ion has a charge of 1 +.
A neutral ion would have the same number of protons and neutrons. The neutrons have no charge (they're neutral) so they don't matter when it comes to the charge of an ion. This ion has 30 protons (+) and 29 electrons (-). There is 1 more proton than there are electrons so the ion has a charge of 1 +.
Explanation:
It is given that,
Delfino is pushing the box with a force of 10 N to the left. Aleida is pushing the box with a force of 15 N to the right.
Aleida is exerting more force. He is the more stronger individual.
Net force is given by :
F = -10+15
F = 5 N
So, the net force is 5 N and it is in right direction.
Answer:
a.)alkene
b.)alkane
d.)alkana
about c..I think there is something wrong with the question
Answer:
Chemical reactions are represented on paper by chemical equations. For example, hydrogen gas (H2) can react (burn) with oxygen gas (O2) to form water (H20). The chemical equation for this reaction is written as: The '+' is read as 'reacts with' and the arrow '' means 'produces'.
