Assuming P (usually written in upper case) represents a force normal to a given cross section.
If a point load is applied to any point of the section, stress concentration will cause axial stress to vary.
The context of the question considers the uniformity of axial stress at a certain distance away from the point of application (thus stress concentration can be neglected).
If a force P is applied through the centroid, sections will be stressed uniformly. However, if the force P is applied at a distance "e" from the centroid, the equivalent load on the section equals an axial force and a moment Pe. The latter causes bending of the member, causing non-uniform stress.
If we assume A=(uniform) cross sectional area, and I=moment of inertia of the section, then stress varies with the distance y from the centroid equal to
stress=sigma=P/A + My/I
where P=axial force, M=moment = Pe.
Therefore when e>0, the stress varies across the section.
Answer:
none
Step-by-step explanation:
p=lw
24, not squared
if your are calculating the perimeter of area, then it would be squared
Answer:
No, it is much too low
Step-by-step explanation:
If he sold out 2 performances at around 4000 seats, we would expect the estimate to be 8000 at least, which is way higher.
The total amount that Penny has budgeted for her trip to Egypt is £5351.62.
<h3>What is the total amount budgeted for the trip?</h3>
The exchange rate is the rate at which one currency is exchanged for another currency. The total amount that was budgeted by Penny is the sum of the different compoments that she compiled for the trip.
Cost of international phone card in Egyptian pound = 41.38 x 5.3841 =£222.79
Cost of passport in Egyptian pound = 65 x 5.3841 = £349.97
Total cost = 3,241.77 + £222.79 + 494.25 + £349.97+ 398.26 £ + 644.48 = £5351.62
