A pin-connected truss is loaded and supported as shown. Each aluminum member has a cross-sectional area of A = 2.4 in.?. Assume a :
3.50 ft and b = 4.20 ft. If the normal stress in each member must not exceed 50 ksi, determine the maximum load Pmax that may be
supported by the structure.
![A pin-connected truss is loaded and supported as shown. Each aluminum member has a cross-sectional area of A = 2.3 in.². Assume a =
3.75 ft and b = 4.50 ft. If the normal stress in each member must not exceed 50 ksi, determine the maximum load Pmax that may be
