Question 1 An assembly consists of a 2-inch diameter solid aluminum rod and a 1.5 inch diameter solid aluminum rod that is pinned between two rigid walls. The circular bar is initially unstressed. An axial load (P = 5.3 kips) is placed on the solid rod assembly at Point C. 2" 3'-0" E 10,500 ksi (Modulus of Elasticity) Determine bsilqgs the magnitude of the axial reactions at the supports, Points A and C. A to Answer: Axial reaction at support A Axial reaction at support C A 2 B 1.5" 1'-6"-

I think you forgot about the horizontal force at the pin

At which point on the design P-M interaction diagram is the design flexural strength largest? O Pure compression Pure tension Balanced failure point (CCL limit) O TCL limit Beam condition (Pn = 0) %3D //img00.zhaopin.cm
