A rectangular concrete beam has a width of 300 mm and a depth of 500 mm. It is subjected to a shear force of 20 kN. What is the shear stress at a depth of 150 mm from the neutral axis?
A) 1.33 N/mm2B) 2.67 N/mm2C) 4 N/mm2D) 5.33 N/mm2 Reference:As per IS 456:2000, the shear stress formula is:τ = VQ/IbWhere,τ – Shear stressV – Shear forceQ – First moment of area above or below the neutral axisI – Moment of inertiab – Width of beam For a rectangular section, I = bd3/12Q = A x…
