I have a question during my Tensile Test of Sturctural
Steel.
Ive collected all the data, can you calculate the Elastic
Modulus and referring to the stress strain curve of your samples ,
discuss and compare the results, specify the similarities and
differences if there is any and provide possible reasons.
Thanks

Learning Goal: To calculate the shear stress at the web/flange joint in a beam and use that stress to calculate the required nail spacing to make a built- up beam. A built up beam can be constructed by fastening flat plates together. When an l-beam is subjected to a shear load, internal shear stress is developed at every cross section, with longitudinal shear stress balancing transverse shear stress. If the beam is built up using plates, the fasteners used must...
