A beam has an f'c = 5000 psi, fy = 60000 psi, reinforcement ratio = 0.0137. Which of the following is most likely true about the strain in the extreme tension steel? Use the tables posted to Canvas as needed (The ones in the back of the book). The strain is = 0.005

Question 4 A 6 KN force is applied at the free end of a wood (E = 12GPa) beam with dimensions given in Fig. Q4. Neglecting the effect of fillets and stress concentration, determine (a) the maximum compressive stress and its location at section A-A; (b) the maximum shearing stress and its location at section A-A; (c) the deflection at section A-A. 6 kN 300 mm 400 mm ΤΑ 叶 ¡A Fig. Q4 96 mm -- 12 mm 12 mm 48 mm
