Problem 1. A channel shape is under 50 kips dead and 100 kips live tensile axial load as shown in the
figure. The member is connected to a gusset plate with 10 inch longitudinal welds. Find the lightest
channel shape to carry the loading. Use only vielding and rupture limit states to design. Use 50 ksi steel
(Fy=50 ksi, Fu=65 ksi).
(a) Assume yielding limit state controls in the design process;
(b) After selecting the lightest section, check the rupture limit state. Do not redesing if needed.
