NEET Physics (general) MCQ Question
Which of the following statements about shear stress and design considerations for load-bearing structures is correct?
Shear stress is significant for beams under certain load conditions, where specific cross-sectional shapes enhance load capacity.
Shear stress does not affect the design of pillars in buildings and bridges.
All beams should have rectangular cross-sections to ensure maximum strength under load.
The height of structures has no relation to the shear component of stress experienced by materials.
Correct Answer
Detailed Explanation
Statement A is correct as it highlights the importance of shear stress in beams and the role of cross-sectional shapes in load-bearing capacity, as indicated in the context about beam design. Statements B, C, and D misrepresent the influence of shear stress and design principles in mechanical properties.
