The ratio of maximum shear stress to average shear stress of a circular beam, is
A. $$\frac{2}{3}$$
B. $$\frac{3}{2}$$
C. $$\frac{3}{4}$$
D. $$\frac{4}{3}$$
Answer: Option D
Solution (By Examveda Team)
Shear stress is the stress induced when a force is applied parallel or tangential to the surface of a material.Average shear stress is calculated as the total shear force divided by the cross-sectional area.
Maximum shear stress is the highest shear stress value in a beam's cross-section, and in the case of a circular cross-section, it occurs at the neutral axis.
For a circular beam, the relationship between maximum shear stress and average shear stress is given by:
τmax = (4/3) × τavg
Therefore, the ratio of maximum shear stress to average shear stress is:
τmax / τavg = 4⁄3
This means the maximum shear stress is 1.33 times the average shear stress in a circular beam
Hence, the correct answer is Option D: 4⁄3

Is it correct for rectangular , it is 3/2 ?
@Muhammad Saqib.
Can u plz Explain!!!
While in rectangular it is 3/2
