Roof truss experiment lab report discussion.
The truss in class session.
Introduction the purpose of this lab report is to analyze how accurate the theoretical analyses of different trusses are.
Academia edu is a platform for academics to share research papers.
For larger spans a truss with a polygonal upper cord such as the parker truss is used for some savings in material.
You will choose one of the strain gages and use the p 3500 strain indicator to measure the strain.
What you will do in the lab.
The most common form is the warren truss with verticals.
In the engineering term the truss is defined as the two force member where the members are so assembled that the.
Lab report for engineering lab 2.
The first is between load and the shear force with load is on y axis and shear force is on x axis.
For this purpose two of the four aluminum made trusses namely warren truss and pratt truss are analyzed first experimentally and than theoretically.
The truss structure consists of members elements that takes only tension or compression and no bending moment in what so ever form.
Shear force in a beam lab report aim.
Truss structures lab report experimental procedure 4 results 5 discussion 6 conclusion 7 2 truss structures lab report abstract this experiment involved the creation of a warren truss bridge in an attempt to experimentally validate the mathematical methods commonly used to theoretically evaluate structural stability and integrity.
Common types of trusses bridge trusses in particular the pratt howe and warren trusses are normally used for spans up to 61 m in length.
In class wednesday 11 26 08 overview a three dimensional truss is tested under transverse loading and the load deflection characteristics and the internal bar member strains are measured.
You will apply the load at the center of the truss as shown and record the strain.
The instructions to set up the strain gage are given on the p3500 box.
