A rigid mass of (1 mathrm{~kg}) drops from a height of (1 mathrm{~m}) onto a simply supported
Question:
A rigid mass of \(1 \mathrm{~kg}\) drops from a height of \(1 \mathrm{~m}\) onto a simply supported aluminum beam at the center (figure 8.14). Use Newmark time integration to calculate the maximum impact force and impact duration. Plot the center deflection of the beam as a function of time. The dimensions of the beam are: \(1 \times 1 \times 30 \mathrm{~cm} ; E=70 \mathrm{GPa}\), and density \(ho=2,700 \mathrm{~kg} / \mathrm{m}^{3}\).
