A building's entrance canopy is constructed as a fixed slab attached to one of its longer sides. The slab has dimensions of 2.50 m x 6 m and a thickness of 225 mm. It is designed to bear various loads, including a uniform live load of 2000 Pa, a uniform dead load of 5000 Pa (excluding the weight of the slab itself), and a concentrated dead load of 5000 N per meter applied at the far end of the support. The design of the slab ensures that the main bars are oriented parallel to the shorter span. The specified design properties include a compressive strength (fc') of 21 MPa, a yield strength (fy) of 345 MPa, 16-mm-diameter main bars, 10-mm-diameter temperature bars, and a clear cover of 20 mm. The unit weight of the concrete is 23,544 N/m3. Find: 1. Determine the spacing of the main bars in mm 2. Determine the spacing of the temperature bars in mm
