SOLVED: Problem 1 (10 Points): The composite beam consists of a wood core (Ew = 10 GPa) and two steel plates (Es = 200 GPa). If the allowable bending stress for the wood is Sallow = 20 MPa, and for the steel is Sallow = 150 MPa, determine the maximum moment (My) that can be applied to the beam. The dimension (d) of the cross-section is given in the table below for each student. Hint: transform wood to steel.20 mm 75 mm20 mm

The composite beam consists of a wood core and two plates of steel. If the allowable bending stress for the wood is (σallow )w=20 MPa, and for the steel (σallow )st=130 MPa, determine the maximum moment that can be applied to the beam. Ew=11 GPa, Est=200 GPa | Numerade

The composite beam is constructed from wood and reinforced with a steel strap. Use the method of Sec. 6.6 and calculate the maximum shear stress in the beam when it is subjected to a shear of V=50 kN. Take Est=200 GPa Ew=15 GPa | Numerade
