Question 3 The global system equations, {F} = [X]{D), for a ID spring assemblage is shown below. Produce a schematic of the spring assemblage and include any boundary conditions and external forces that are reflected in the force vector and displacement vector. Label the degrees of freedom (uj, u2, us, w4), spring stiffnesses (ki, k2, ka, ka), and any external forces. KI+ KA -KI -KA 0 Fir -200016 0 -ks ka + KA 0 300016 0 -12 0
