5. Concept Generation Pedal Box Undertray Chassis

6. Plan for 12/12 Ryan BaldiSource material and machining facility for plugs. Dave HollandObtain rough material properties. Obtain rough chassis model. Begin work in ANSYS. Aid with bell crank mounting concepts. Martin IwanowiczResearch rules compliance. Obtain loads for chassis from rigid body kinematics. Ted KusnierzFinalize pedal box geometry and start analysis. Anthony SalvoDevelop undertray geometry and start analysis. Charles ThomasContinue development of chassis geometry. Generate concept for front roll hoop mounting and bell crank mounts
