Design a rectangular beam section for the condition given below. Use f = 28 MPa and fy = 420 MPa, and beam weight is not included. Sketch the strain and stress profiles and the resultant section. wwwww 00 IN /

You must have to draw FBD

2. Per ACI318-19, choose the correct value of the strength reduction factor ø for the flexural capacity of a beam with ɛ = tension face. 0.0032, where & is the strain for steel reinforcement closest to the (A)0.9 (B) 0.85 (C) 0.75 (D)0.65

2- For the cross section shown: i) determine the cracked moment of inertia (ler) using n=8, and ii) using transformed-area method determine stresses in concrete and steel if subjected to a moment M = 150 ft-kips. As = 4.1 in ² Assume f. = 4,000 psi, and f, 60,000 psi. 14"-wide hole As 20" e 6 3* 60 13
