3. Finished Layout Drawings New layout drawings with air compressor and latches

4. Engineering Analysis Force Analysis Total Force Calculations

5. Engineering Analysis Cont. Deflection Analysis

6. Engineering Analysis Cont. Deflection Analysis Cont. for deflection in the center lines of all lips, this is unacceptably high change quantity of supports from 4 supports to 8 supports

7. Engineering Analysis Cont. Clamping Force

8. Engineering Analysis Cont. Buckle Tensile Strength Total tensile strength must be greater than 600 lb. Assume using steel as the buckle material with a UTS of 120000 psi. With a safety factor of 2, d=.08 in

9. Engineering Analysis Cont. Buckle Tensile Strength Cont. Use 1/8” diameter rods for the buckles, this will give 1473 lbs of force per side, this yields a total force of 2945 lb.N. Areas of ConcernSolutions -Where the buckle meets the plastic-Expand Contact Area of Buckler -Deflection of the lid.-Brace Lid - Bowing of the sides of the container-Brace sides or choose different materials

10. Engineering Analysis Cont. Tolerances Around the seal, 1/32” Elsewhere on the box, 1/8” The cart tolerances are ¼” Cart Analysis Cart Load Analysis F = 28 lbs F/4 = 7 lbs Compressive force on all four legs is 7 lbs

11. Engineering Analysis Cont. Weight and Dimensions H x W x D Weight -18” x 18” x 18”, Container-18 lbs for box -6” x 6” x 18”, Compressor-10 lbs for compressor -30” x 30” x 20”, Cart-30 lbs for Cart

12. Engineering Analysis Cont. Material Selection Analysis CES Software of Price/Density vs. Young’s Modulus (stiffness)/ Density

13. Engineering Analysis Cont. Material Selection Analysis Cont. CES software of the Tensile Strength vs. price for the latches of the buckles
