For the concrete beam shown, the modulus of elasticity is 25 Gpa for the concrete and 200 GPa for the steel. Knowing that b= 200 mm and d-450 mm, and using an allowable stress of 12.5 MPa for the concrete and 140 MPa for the steel, calculate (a) the required area As of the steel reinforcement if the beam is to be balanced, (b) the largest allowable bending moment. Hint: The design of a reinforced concrete beam is said to be balanced if the maximum stresses in the steel and concrete are equal, respectively, to the allowable stresses os and oc.

A steel bar is attached to a wood support beam with four 22 mm diameter lag screws, as shown in the figure. The steel bar is 69-mm-wide by 8-mm-thick. For the steel bar, the yield strength is 235 MPa and the ultimate bearing strength is 350 MPa. The ultimate shear strength of the lag screws is 155 MPa. Factors of safety of 1.70 with respect to yield strength and 3.0 with respect to bearing strength are required for the bar. A factor of safety of 2.9 with respect to the ultimate shear strength is required for the lag screws. Determine the allowable load P that can be supported by this connection. (Note: Consider only the gross cross-sectional area of the bar-not the net area.) Support beam Answer: Pallow= 0000 P Steel bar KN
