Unformatted text preview: 0 kN/m Geometric Properties Block base = 1 m width = 1 m height = .5m Pan base = 2 m width = 2 m height = .25 m Spring length = 6m Loading The block is dropped from rest at a height of 2 m. g = 9.81 m/sec2 Analysis Assumptions and Modeling Notes The sizes of the block, pan, and spring have been arbitrarily selected. The densities of the block and pan, however, are based on the respective volumes of each component. A relatively course mesh was chosen for both the block and pan.
