Soil erosion is a widespread problem in rural and urban Queensland. If we want to save our soils, we need to understand the different types of erosion that can occur. Queenslandâs high intensity summer rainfalls represent a significant risk of erosion by water.
Lagrangian function. Lagrangian function, also called Lagrangian, quantity that characterizes the state of a physical system. In mechanics, the Lagrangian function is just the kinetic energy (energy of motion) minus the potential energy (energy of position).
Use the Lagrangian approach to find the angular frequency of small oscillations about the top position. Note the moment of inertia of the cube I = 2mb2/3 and for the small angle approximation: sin Î¸ â Î¸ and cos Î¸ â 1.
