Department of Mechanical Engineering MICHIGAN STATE UNIVERSITY ME 457: Mechatronic System Modeling & Simulation Problem Set #2. (2.1) Do text problem 4-3(a). Make a free body diagram, make a bond graph model, and generate a set of equations. (2.2) Do text problem 4-3(b). Make a free body diagram, make a bond graph model, and generate a set of equations. (2.3) Do text problem 4-3(g). Make a free body diagram, make a bond graph model, and generate a set of equations. (2.4) Consider the "quarter-car" model shown in Figure 2-1 below. The vector "g" denotes the effect of gravity. The variable y gnd (y-ground) denotes the elevation of the road surface as a function of time, as the car travels along the road. Assume that is measured in an inertial reference frame. Note that the car has vertical and horizontal motion. The horizontal motion is an input for our study. Figure 2-1. Quarter-car model schematic. (a) Estimate reasonable
