Transcribed Image Text:4 Problem
Consider an aluminum rod of length L = 2 m and cross-sectional area A = 0.01 m² (shown on the
left). Attached to the rod tip is a concentrated mass mc = 10 kg, and a force u(t) is applied which
causes a small amount of extension/compression of the rod. An equivalent lumped parameter

model of the system is shown on the right. Assume that the density of aluminum is p
kg/m³ and Young's modulus is E 68 x 10 Pa.
Using the lumped parameter tables from Lecture 15 to find:
⚫ the equivalent lumped mass me
⚫ the equivalent stiffness k
using the above expressions determine the transfer function G(s) = X(s)/U(s).
