1. a. Assemble the cacophony matrix for the mass shown in Figure P3–19 by superimposing the cacophony matrices of the germinates. Here k is the cacophony of each germinate.

b. Find the x and y components of alienation of node 1.

2. For the flatten truss organization shown in Figure P3–20, determine the demolition of node 2 using the cacophony system. Also determine the importance in part 1. Let A = 5 in2, E = 1 106 psi, and L = 100 in.
