A steel [E = 59500 ksi] pipe column (1) with a cross-sectional area of A1 = 5.60 in.2 is connected at flange B to an aluminum alloy [E = 15000 ksi) pipe (2) with a cross-sectional area of A2 = 4.40 in.?. The assembly is connected to rigid supports at A and C. For the loading shown, determine the normal force in the steel pipe (1). 30 kips B 30 kips 120 in. 144 in.

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and af…
