5. A metal has a modulus of elasticity of 70 GPa, yield strength of 210 MPa, Poisson's ratio 0.33 and an area of cross section of 9 mm? A. Calculate the area of cross section when a tensile stress of 140 MPa is applied on this metal (6 points) B. In a new experiment, a stress of 280 MPa is applied on this metal. Then the stress is completely removed. Again a stress of 350 MPa is applied. Then this...
1. Draw a schematic stress-strain diagram for steel. Make sure you mark all the important points and regions on it. Provide a one-two sentence explanation for each point and region along the diagram. 2. A cylindrical specimen of a nickel alloy having an elastic modulus of 207 GPa (30 x 10* psi) and an original diameter of 10.2 mm (0.40 In.) will experience only elastic deformation when a tensile load of 8900 N (2000 Ibe) is applied. Compute the maximum length...
Chapter 06, Problem 6.50 A steel alloy specimen having a rectangular cross section of dimensions 19.0 mm x 3.2 mm (0.7480 in. x 0.1260 in.) has the stress-strain behavior shown in the Animated Figure. If this specimen is subjected to a tensile force of 100900 N (22680 lbf) then (a) Determine the amount of elastic strain induced. (b) Determine the amount of plastic strain induced. (c) If its original length is 400 mm, what will be its final length after...

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
