Q.2) A simple beam of span length 3.2 m carries a uniform load of intensity 48 kN/m. The cross section of the beam is a hollow with wood flanges and steel side plates, as shown in the figure below. The wood flanges (E = 10 GPa) are 75 mm by 100 mm in cross section, and the steel plates (E = 210 GPa) are 300 mm deep. What is the required thickness t of the steel plates if the allowable stresses are 120 MPa for the steel and 6.5 MPa for the wood?

A steel beam is 24 inches tall, has a length, L, of 32ft, and has a yield stress of 36ksi. The simply supported beam supports a single load, P, of 17 kips at its midspan. If the theoretical maximum deflection of this beam is -(PL^3)/(48EI), determine the required moment of inertia such that the actual deflection of the beam will not exceed a value of L/360, and the actual stress will have a factor safety of 1.5 with respect to yielding.
A concrete beam is reinforced by three steel rods placed as shown. The modulus of elasticity is 3* 106 psi for the concrete and 30 *106 psi for the steel. Using an allowable stress of 1350 psi for the concrete and 20 ksi for the steel, determine the largest permissible positive bending moment in the beam.
