Question
![A simple rigid structure ABC is to be built to hold load at C as shown in Figure QS.
Support AE is to hold point A by pin at both ends. Support BD is to support point B
with pin joint at both end.
Support AE is made made of steel with E= 200GPA, ay = 250 MPa with solid circular
cross section of 30 mm diameter. Support BD is made of akaminum alloy with E-
180GPA, oy = 150 MPa with rectangular tube cross section as shown in figure.
If LAz= 2.0 m and LED= 2.5 m
Find the maximum load P that can be applied at C for them not to fail by buckling.
