Which risk increases when induced transverse shear exceeds concrete's capacity in a reinforced concrete beam?

💡 Explanation

When transverse shear exceeds concrete's capacity, diagonal tension cracking occurs because the concrete's tensile strength is weaker than its compressive strength, leading to crack initiation and propagation. Therefore diagonal tension cracking is a primary risk, rather than yielding, spalling or buckling, which result from exceeding different material limits or instabilities.
