12. Assume a uniformly load simply support beam with a rectangular cross section. The width of the beam is fixed by other design considerations. Determine the ratio between the difference in depth required for an aluminum beam compared to a steel beam in order to obtain the same maximum deflection. MOE aluminum can be taken as 10,000 ksi, for steel as 30,000 ksi. The maximum deflection for the beam is 5wl*/384EI Factoring the deflection equations we can conclude that for equal deflection Eala = Esls where subscripts a and s represent values for aluminum and steel. The depth of must be times the depth of the

g) the maximum bending stress in timber. Enter your answer in MPa to 2 decimal places.

A wood beam reinforced by an aluminum channel section is shown in the figure. 150 mm 230 mm 38 mm 6.5 mm -163 mm- The beam has a cross section of dimensions 150 mm x 230 mm, and the channel has a uniform thickness of 6.5 mm. If the allowable stresses in the wood and aluminum are 8 MPa and 50 MPa, respectively, and if their moduli of elasticity are in the ratio 1 to 6, what is the maximum allowable bending moment for the beam? Enter the magnitude in kN · m. (Assume that the component parts of the beam are securely bonded by adhesives or connected by fasteners. Also, be sure to use the transformed-section method in the solution.) (No Response) 14.06 kN· m
