Unformatted text preview: it deep into the ground. After each hit, the weight is lifted up and dropped again, until the pile is securely planted in the ground. Assume that the ground can be represented by a viscous damper with damping coefficient b. Also assume that h remains the same for each hit. a) Draw a schematic of the system using basic modeling elements. Treat the weight as being stuck on top of the pile for each driving stroke. b) Draw FBDs for each basic element. c) Derive the equations of motion. d) Determine initial conditions for the combined masses just as the weight hits the top of the pile the first time. Problem 3 : (35%) Problem B-3-14 (p. 103 of Ogata text)...
