1: A beam-column system is designed to sustain a distributed load w=1 kN/m. The beam is made of wood with a square cross-section of 300 x 300 mm2. The wood has ultimate stresses under tension and compression of 2.5 MPa and 30 MPa, respectively, and ultimate stress under shear of 6.5 MPa. The column is made of aluminum with a yield limit of 30 MPa and an elastic modulus of 70 GPa. A safety factor of 2 is desired. a) Determine whether the beam is safe. b) Determine the diameter of the column to avoid failure
