    This report has been written to describe an experiment performed on a channel section examining the stiffness of the beam through two differing types of deformation – curvature and deflection. The aim of the experiment was to determine the value of the flexural rigidity (EI) in two different ways; using the curvature, k, and the mid-span deflection. The testing method used for the experiment is described. The experiment found that the EI values calculated were as follows: - EIcurv = 1.76E+10 Mpa.mm4 when calculated using the curvature, k. - EIdefl = 1.77E+10 Mpa.mm4 when calculated using the mid-span deflection.…

    The alloy steel is a material very resistant capable of withstanding forces of grate magnitude either tension or compression. Steel is not an element; it is an alloy of iron containing less than 1% carbon to make it stronger. The process of steelmaking had multiple changes in the last century to meet regulations based on the political, social and technological atmosphere, especially in the last decades since global warming became the most important factor. Steelmaking involves three steps which are melting, purifying and alloying. In the alloying process it is mixed with other elements such as manganese, nickel cobalt; depending on the desired alloy properties. The density of the alloy steel is 7850 kg/m^3, the elastic modulus is 190-210 GPa and the yield strength is 366-1793 MPa. These properties make the alloy steel the most suitable material for the Tomcat from an engineer’s perspective.…

    A tensile test was performed on a 4140 steel sample and the axial and transverse strains were measured. Data points were collected at incremental loads and graphed to determine the elastic modulus (30.4 x 106). Poisson’s ratio was also calculated from the dataset and determined to be 0.29. These experimental values agree closely (within 2%) to the textbook values of the steel sample. A sample of 7075 Aluminum was used in a cantilever beam test. Intermediate and end loads were place on the sample and the strain was measured at various distances from the loads. Using the dataset from the individual loads, the superposition strain was calculated and agreed within 7% of the experimental strain with both loads. From the measured deflection of the cantilever beam and the dataset, Young’s Modulus for the aluminum sample was determined to be 9.1x106 psi which agrees within 8% of the textbook value.…
