For the plane trusses supported by the spring at node 1 determine the nodal displacements and the stresses in each element. Let E 210 GPa and A = 5.0 x 10-4 m2 for both truss elements. solve using finite element methods

Handwriting not allow please And give me complete answer

XYZ is deciding whether to weld bicycle frames manually or to purchase a welding robot. If welded manually, investment costs for equipment are only $10,000. The per-unit cost of manually welding a bicycle frame is $50.00 per frame. On the other hand, a robot capable of performing the same work costs $400,000. Robot operating costs including support labor are $40.00 per frame. At what volume would XYZ be indifferent to these alternative methods? *
