4. Chassis
2” x 4” wall
Rectangular and square A36 mild steel tubing
-Yield strength of 36,000 psi
Simple 90 and 45 degree angles
-Simplify fabrication
-Reduce production costs
Final design of the frame came to a total weight of 729 lbs.

5. Chassis Displacement - 1000lb applied to front suspension mount
Max displacement: 0.504”
Max Von Mises -1000lb applied to front suspension mount
Majority of frame at <6,000 psi von Mises stress, SF ≈ 6.0
Displacement - Max Displacement w/ 250lb per module:
Max von Mises Stress w/ 250lb per module: ,670 psi, SF = 2.05
