alleryStart learning →Maximum shear stress in a rectangular beam relative to average shear stress is:
A1.5 × τ_avg (= 1.5 × V/A)
B1.0
C2.0
D1.33
Answer & Solution
Correct answer: A. 1.5 × τ_avg (= 1.5 × V/A)
τ_max = 1.5 × V/A for rectangular.
**For I-section:** 1.0-1.1 × V/A_web (shear mostly carried by web).
**For circular:** 4/3 × V/A. Used to check shear adequacy.
