Singly Reinforced Beam - Moment of Resistance Problems

Find the moment of resistance, depth of neutral axis and lever arm of a beam section with width 250 mm, effective depth 360 mm and reinforced with 3 Nos 16 mm dia. bars. Use M25 concrete Fe 415 steel Find the moment of resistance of a singly reinforced concrete beam of 200.3 mm width and 428.2 mm effective depth, reinforced with 4 bars of 14 mm diameter of Fe415 steel. Take M15 concrete. Find the moment of resistance of a singly reinforced concrete beam of 200 mm width and 400 mm effective depth, reinforced with 4 bars of 16 mm diameter of Fe415 steel. Take M15 concrete. A rectangular beam of size 300 mm × 450 mm is required to resist a moment of 28 kNm. Find the reinforcement required for the beam. Use M25 concrete Fe 500 steel A rectangular beam has width of 250 mm and resists ultimate moment of 220 kNm. Find the minimum effective depth. Use M20 concrete Fe 415 steel
