The figure shows a weapon called a battering ram (modern large battering rams are typically mounted on armored vehicles). The ram has a weight w, = 2500 lb, center of mass at E, and radius of gyration kE = 6.5 ft. Also let the distance between points A and B and between points C and D be 6 ft. In addition, let h 4.5 ft and d = 3 ft. Finally, let the connections at points A, B, C, and D be pin connections, and assume that the cart does not move while the ram swings. Assume that AB and CD are uniform thin rods weighing 100 lb each and that the ram is at rest with 0 = 0°. Assume that bar CD breaks suddenly, and determine the acceleration of E and the forces at A immediately after CD breaks. ram ED

Buckling of columns

The column is described as a vertical member of the structure that carries an axial compressive load, and buckling is a lateral deformation of the column under the application of load.

Obtain the moment of inertia () of the flywheel from its dimensions (see figure below). Note that the flywheel is two cylinders of diameter 0.03086 m and one cylinder of diameter 0.2008 m. (For uniform cylinders, /= 1/2(MR2)) Since the masses are unknown, express the mass as the density (p) times the volume. Each part of the flywheel is made of the same material so there is only one density. You should now have an expression for the density in terms of I, the two diameters, the two thicknesses, and constants. 0.0520 m 0.03086 m 0.2008 m 0.0155 m
