Question
The shear stress formula does not provide accurate results when applied to members having cross-sections that are short or flat. True or False?
Solution
True. The shear stress formula is based on the assumption of a long, slender, circular cross-section member where the shear stress is uniformly distributed. For short or flat cross-section members, this assumption does not hold true and the shear stress distribution is not uniform, leading to inaccurate results when using the standard shear stress formula.
