Dynamics of Structures

The aluminum beam shown in Figure P8.5 carries a small hoist weighing 450 N. Calculate the frequency of vibration when the hoist is at a distance of $1.2 \mathrm{~m}$ . from one support. What are the lowest and highest frequencies and the corresponding hoist locations? $E=69,000 \mathrm{MPa}$ and $\rho=2770 \mathrm{~kg} / \mathrm{m}^{3}$ for aluminum.
