Question

of 25 mm is pulled in tension with a 44,500 N force producing only elastic detormation . What is oreonding strain and the length between the gage marks when subjected to this force? Given: elastic modulus of copper is 105 GPa. 5. A 10-mm diameter bar of 1040 carbon steel is subjected to a tensile load of 50,000 N, taking it beyond its yield point. Calculate the elastic recov removal of the tensile load. Given: elastic modulus of steel is 200 GPa, yield and ultimate tensile strength of steel are 600 and 750 MPa, respectively ery (or elastic strain) that would occur upon 6. A ceramic sample with a flexural strength of 600 MPa is subjected to a three-point bend test. The dimensions of the sample are 100 mm long, 15 mm wide, and 6 mm thick. The distance between the support points is 75 mm. At what force will the ceramic break? 7. A tensile tst was conducted on a type 304 stainless steel sample and the load-elongation data in the table below was obtained. The initial sample gage length and gage diameter were 50.8 and 12.7 mm, respectively. The final length and diameter of the sample after fracture were 66.040 and 7.62 mm, respectively.
