A tensile test was performed on a metal specimen having a circular cross section with a diameter 0. 510 inch. For each increment of load applied, the strain was directly determined by means of a strain gage attached to the specimen. The results are, shown in Table: 1.5.1. a. Prepare a table of stress and strain. b. Plot these data to obtain a stress-strain curve. Do not connect the data points; draw a best-fit straight line through them. c. Determine the modulus of elasticity as the slope of the best-fit line.
QUESTION: The distributed load on the T-section beam shown below and moment affects. A is the fixed joint and B is the sliding joint. This beam is made of a ductile material with a yield stress (σak) of 1000 MPa. The thickness (depth) of the beam profile is t=6 mm. A) As a mechanical engineer, check the strength of this beam (in terms of Normal and Shear Stress) ? B) In order for the existing beam to run smoothly, two 100x25 mm plates made of the same material are planned to be welded to this beam. The mechanical engineer working in the factory told the welder to weld this piece under the beam (where the B point is). But the welder, regardless of what the mechanical engineer said, welded this plate to both sides of the existing T-section beam as shown below, thinking that it wouldn't matter anyway. As a mechanical engineer : 1) After welding these plates on both sides of the beam, as the welder did, find out whether the new beam will work smoothly or not by making the necessary…
