MAST STORAGE RACK Philip Crist Max Carpenter Sean Ellis Gershom Obeng

Current Progress 0 Met with shipyard right before break and finalized all requirements for design. 0 Finished preliminary Solidworks drawings 0 Created FEA models for cantilever deflection and simple beam analysis

Current Design 0 Durable frame constructed from I-beam steel 0 Rectangular base with I-beam supports bolted to the floor 0 Steel plate welded to base support beams 0 Vertical members welded with rigid L-brackets 0 Vertical members to attach various clamps 0 Bracing along vertical members 0 Drip pan to catch and drain residual oils 0 12’ x 12’ footprint 0 Weight requirement of approximately 10,000lbs
