Question

Consider two bar elements under a force at the tip. Using the displacement controlled method, plot the load-displacement curve (F vs. u₂ and u₃). Increase the tip displacement u₃ up to 1.0 m by ten equal increments.

Assume St. Venant-Kirchhoff material with E = 100 MPa and crosssectional areas of A⁽¹⁾ = 1.0 X 10^-4 m² and A⁽²⁾ = 0.5 X 10^-4m².
