Question

A concrete floor slab of 140 mm thick is reinforced by 16mm dia steel rods placed 38mm above the lower face of the slab and spaced 150mm on center. The distance from the upper face of slab to steel is 100mm. The modulus of elasticity is 25 MPa for concrete and 200 MPa for steel. Knowing that bending moment of 4.5KN-M is applied to each 0.30 m width of slab, determine the maximum stress in the concrete and steel respectively
(a) 12.9 Mpa & 177.8 Mpa
(b) 1.29 Mpa & 1.778 Mpa
(C) 129 Mpa & 17.78 Mpa
(d) 0.129 Mpa & 0.177 Mpa
