At the limit state of collapse, an R.C. beam is subjected to flexural moment 200 kN-m, shear force 20 kN and torque 9 kN-m. The beam is 300 mm wide and has a gross depth of 425 mm, with an effective cover of 25 mm. The equivalent nominal shear stress ^{$(\tau_{ve})$}as calculated by using the design code turns out to be lesser than the design shear strength ^$(\tau_C)$of the concrete.

The equivalent shear force (V_c) is
