1.5-7 The data shown in the table were obtained from a tensile test of a metal specimen with a rectangular cross section of 0.2 in.² in area and a gage length (the length over which the elongation is measured) of 2.000 inches. a. Generate a table of stress and strain values. b. Plot these values and draw a best-fit line to obtain a stress-strain curve. c. Determine the modulus of elasticity from the slope of the linear portion of the curve.

A piece of 50 mm x 30 mm material experiences a homogenous deformation as shown in the figure below. The deformed shape in x-y plane is illustrated by the solid lines. If E = 3.9 GPa and the Poisson's Ratio is 0.35, what is the associated shear stress? provide your answer in MPa with precision to two decimal points. Answer: 0.014 30 0.010 y 0.009 0.012 50

Learning Goal: To determine the average normal strain and average shear strain in a known material based on a given load and geometry. A flat plate ABCD distorts into the dashed shape ABCD shown after a load is applied with a= 165.0 mm, b =49.0 mm. g= 6.0 mm, f=14.0 mm, and e=7.0 mm.

A tensile test was conducted on a specimen with a diameter of 0.5 in. A strain gage was bonded to the specimen so that the strain could be obtained directly.
