Project 3: Wood Beam Design
Transcript of Project 3: Wood Beam Design
Moment of Inertia
Phone First Attempt Requirements Presentation Overview Objective
Lessons Learned Beam Requirements
Only basswood and wood glue
Mass < 200 g
Max cross-section 2" x 2"
Cost < $9.00
2 or more pieces of wood glued together
Load: 275 lbf
Deflection < 0.1" between 18" Planning Prepare Gantt Chart
Turn in individual designs
Comprise a decision matrix Status: Passed
Beam Mass: 186g
Flange Thickness: 3/16"
Web Thickness: 3/16"
Base: 1 11/16"
Moment of Inertia:0.837in^4
Modulus of Elasticity:1.5x10^6 Second Attempt Status: Failed
Did not compensate for glue in deflection
Over-testing caused wood to weaken
Compensated for error in calculations
Accuracy in construction
Increase the safety on the deflection
Reinforce glue joints for strenght Status: Failed
Given the wrong Modulus of Elasticity
Found a more accurate modulus of elasticity Ready for constuction! Final Design Management skills
Cordinating team roles
Team member input
Types of beams
Inertia and deflection
Modulus of elasticity Second Attempt Video Lessons Learned
