Solve Prob. 4–80, using beam elements. Model the problem two ways: 

(a) Model the entire wire form, using, 200 elements. 

(b) Model half the entire wire form, using 100 elements and symmetry. That is, model the form from point A to point C. Apply half the force at the top, and constrain the top horizontally and in rotation in the plane.

Data from 4-80

For the steel wire form shown, use Castigliano’s method to determine the horizontal reaction forces at A and B and the deflection at C.
