Bridge Design. Engineering Research Assignment.

Project‐01: Bridge Design
Due Date: Sunday, April 26, 2020 by 11:59 pm (Submit softcopy in Blackboard)
1. OBJECTIVES:This design project is intended to give hands-on exercise on the use of various stages of the design process; i.e,problem definition, generation of goals and criteria, generation of alternatives, assessment of alternatives,evaluation and decision making, planning, testing, and communication of the design. Each design team is expectedto perform a thorough search, generate imaginative and creative ideas, evaluate and assess them thoroughly usingappropriate criteria and various techniques discussed in the class, and then, construct a model for the proposeddesign. Simple design calculations using MDsolid software and experimental testing are required.The learning outcomes from this project are summarized in the following:
 Demonstrate creative thinking,
 Demonstrate an understanding of modern engineering design methodology.
 Assess a specific design through simple design calculations using MDsolid software,
 Design a simple setup for experimental testing and assess a specific design through simple testing,
 Work in small groups on simple conceptual design projects,
 Communicate and present the design to others
In general credit will be given for the following two main aspects of the project:
- Results of experimental testing of submitted project.
- Thoroughness and appropriateness of testing designed testing procedures and calculations.
- Submitted report (from the points of view of quality, followed procedures, intense of study of various designstages).
- Competition results.
2. PROBLEM STATEMENT:
It is required to design a bridge that will be subjected to a static vertical load at its mid-span. The main objectiveis to have a maximum load carrying capacity for a given weight without exceeding certain specified displacementand to be able to predict this capacity accurately. The proposed model is to be fabricated and submitted for testingaccording to the procedures described below. The submitted structure must meet the design specification listed initem number 3.
3. DESIGN SPECIFICATIONS:
DIMENSIONS:
Length: 70 cm ± 2.5 cm Width:12 cm maximum
Height: 15 cm ± 1.0 cm (Height will be measured from the highest to the lowest point in the structure). The general shape of the bridge will fit in a box (as shown in figure-1) with dimensions 70x12x15 cm. The topsurface or upper deck of the bridge must have a flat portion in the mid-span of at least 10 cm long and 12 cmwidth to allow for the loading platform. Also there should be no members that would interfere with the loadingbar right at the center line of thebridge.15 cm70 cm 12 cmMATERIAL:The structure will be made entirely out of wood and wood glue. Use very light wood with cross section 0.5 x0.5 cm.
A report explaining how you designed your bridge in MDsoild, using MDsoild software to design the bridge assuming the force from the test is 200N You need to use screen shots from the software to show the steps and the results. Also the report should include a description on how you applied the design method stages, Use Engineering report format,No prototype build is required.
the reported should be done using MDsoild software and i need screenshots
