COMPUTATIONAL MODELLING AND ANALYSIS 2

1. give the structure of the bridge

2.identify 3 critical points

3.identify the zero-force member and two-force member of joint

4. add 500N force on point1,2 and 3 seperately, identify member force of critical point.

  write down calculations

5. add 700N force on point1,2 and 3, identify member force of critical point.

6. add 900N force on point1,2 and 3, identify member force of critical point.

7. until the bridge break and make the table of truss number with different force and position.

Introduction

A truss is a structure made of numerous littler parts. When developed of wooden timbers, and later including iron pressure individuals, most truss extensions are worked of metal. Sorts of truss extensions are likewise recognized by the terms deck, pony and through which depict the position of the travel surface in connection to the superstructure. The lord post truss is the easiest sort; the ruler post truss adds an even top harmony to accomplish a more drawn out range, yet the middle board has a tendency to be less inflexible because of its absence of askew propping.

comments:

If you choose to do the Bridge Design topic, in this case I can let you just focus on the bridge concept design and load analysis based on calculations. You don't need to physically build and test the bridge, nor need to use any software for simulation. Those parts are useful for the project (particularly in terms of having some hands-on work and applying the skills developed from other courses), but not as directly related to the core knowledge and skill sets required by Mechanics as the design and analysis tasks. So, you can have a conceptual design of a truss bridge and then do the analysis to identify the forces inside the members to discuss whether the design will work, how much the maximum load can be, which members can be of safety concern, and how to modify and improve.

SO u dont have to care about physically build and test. Focus on the truss analysis of the bridge with different force applied on point 1, 2 and 3. And make a excellent table
