Problem 5.12-18 A short length of a channel is subjected to an axial compressive force that has its line of action through the midpoint of the web of the channel [(see figure(a)]. (a) Determine the equation of the neutral axis under this loading condition. (b) If the allowable stresses in tension and compression are 76 MPa and 52 MPa respectively, find the maximum permissible load . (c) Repeat (a) and (b) if two L 76 ± 76 ± 6.4 angles are added to the channel as shown in the figure part (b). See Table E-3(b) in Appendix E for channel properties and Table E-4(b) for angle properties.
