For a 6061 T-6 aluminum beam with dimensions: b = 3.0 cm, d = 0.5 cm, and length, a = 30 cm, (A) what is the maximum mass that can be hung on the end of the beam without exceeding ½ the yield strength at any point in the beam? (B) Where are the maximum stress and strain? (C) What deflection will this cause at the end of the beam? (D)Explain clearly why is there no yield strength listed for wood.
