Q1: An R.C.C. beam of 6 m span is 30 cm wide and has a lever arm of 55 cm. If it carries a U.D.L. of 12 t per m and allowable shear stress is 5 kg/cm2, the beamA is safe in shear
B is safe with stirrups
C is safe with stirrups and inclined bars
D needs revision of section
ANS:D - needs revision of section To determine the safety of the RCC beam under the given conditions, we need to evaluate if the shear stress experienced by the beam is within the allowable limit and whether the necessary reinforcement (stirrups and inclined bars) is provided adequately. First, let's calculate the maximum shear force (V_max) acting on the beam due to the uniformly distributed load (U.D.L.): Vmax=w⋅L/2 Where:
