An R.C.C beam of 25 cm width has a clear span of 5 metres and carries a U.D.L. of 2000kg/m inclusive of its self weight. If the lever arm of the section is 45 cm., the beam is
A)Safe in shear
B)Is safe with stirrups
C)Is safe with stirrups and inclinedmembers
D)Needsrevision ofthe section

Question

Quizplus · Accepted Answer

The beam is considered safe in shear if the shear stress does not exceed the permissible stress for the material, which is determined by the beam's dimensions, the applied load, and the lever arm. Given the information, there's no indication that the shear stress exceeds the permissible limits, hence the beam can be considered safe in shear without additional details on material properties and calculations. Stirrups and inclined members are typically added to enhance shear capacity or when there's a known deficiency, which isn't explicitly mentioned here.
