Draw axial force, stress, strain and displacement diagrams for the structure show below. The cross-section is circular with diameter of 5 feet from A to C, then increasing parabolically to 15 feet at B. Give results in kips, inches and ksi. The material is steel with E=29,000ksi and yield strength of 36ksi. The radius from C to B is given by an equation of the form r=rc​+ax2, where rc​ is the radius at C and a is a constant that is found based on the geometry provided. In this equation x starts at C and goes to the right.
