Maximum shear stress indensity in a beam of circular cross section
Answers
Answer:
Let us consider few examples to determaine the sheer stress distribution in a given X- sections
Rectangular x-section:
Consider a rectangular x-section of dimension b and d
A is the area of the x-section cut off by a line parallel to the neutral axis. is the distance of the centroid of A from the neutral axis
This shows that there is a parabolic distribution of shear stress with y.
The maximum value of shear stress would obviously beat the location y = 0.
Therefore the shear stress distribution is shown as below.
It may be noted that the shear stress is distributed parabolically over a rectangular cross-section, it is maximum at y = 0 and is zero at the extreme ends.
Answer:
Explanation:
When an section beam is subjected to both Bending and Shear Stresses it is normal to find that the Maximum Principle Stress is at the top of the Web. The other possible value is the Maximum Bending Stress which occurs at the outer edge of the Flange
