Roof Truss Experiment Lab Report Discussion

In the engineering term the truss is defined as the two force member where the members are so assembled that the.

Roof truss experiment lab report discussion.

Aim of this experiment is to study the effect of force magnitude on shear forces in a beam. What you will do in the lab. Wednesday friday 11 19 21 08 laboratory report due. The first is between load and the shear force with load is on y axis and shear force is on x axis.

The instructions to set up the strain gage are given on the p3500 box. For this purpose two of the four aluminum made trusses namely warren truss and pratt truss are analyzed first experimentally and than theoretically. The most common form is the warren truss with verticals. 1 0 objective of the experiment 2 2 0 learning outcome 2 3 0 theory 2 4 0 application of truss 6 5 0 procedures 10 6 0 result and analysis 11 7 0 discussion 19 8 0 conclusion 20 9 0 appendix 21 1 0 objective 1 1 the effect of redundant member in a structure is observed and the method of analyzing type of this structure is understood.

You will apply the load at the center of the truss as shown and record the strain. Shear force in a beam lab report aim. Force in redundant truss full report table. Civil engineering baa uploaded by.

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 choose one of the strain gages and use the p 3500 strain indicator to measure the strain. 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.

Lab report for engineering lab 2. Bending moment in a beam lab report. The truss structure consists of members elements that takes only tension or compression and no bending moment in what so ever form. The truss in class session.

Introduction the purpose of this lab report is to analyze how accurate the theoretical analyses of different trusses are.
