Question: problem 2 two rigid masses 1 and 2 are connected...

Question details

Problem 2: Two rigid masses, 1 and 2, are connected by three springs as shown in the figure. Using FE analysis: (a) find the displacements of the two masses (1 and 2); (b) find the element forces in the springs, and (c) the reaction force at the wall (Node 3). Assume the bodies can move only in the vertical direction and cannot rotate. The spring constants (N/mm) are k400, k2) -500, and)500. The masses (kg) are m 20 and m2 40. Take g-10 m/s2 2
