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:
3/20
Step-by-step explanation:
4 1/5 x 1/3 =
<em><u>1 2/5</u></em>
1 2/5 - 1 1/4 =
<u><em>3/20</em></u>
Have a nice day :)
Answer:
A
Step-by-step explanation:
Because it said 100 sea shells and 2 fewer and each bucket.
Bucket B contains 130 which is way more.
Bucket c contains only 80
Bucket D contains 110 so it has to be A.
Have a great day! :)

If every capsule requires 0.007 grams of aspirin, and the druggist has 14 grams, the best way to determine how many capsules he has is to divide 14 grams by 0.007

. This means that he can make C. 2,000 capsules
