Problem 4. An axial strain gauge and a transverse strain gauge are mounted to the top surface of a steel beam that experiences a uniaxial stress of 2222 psi. The gauges are connected to arms1 and 2 of a Wheatstone bridge. With a purely axial load applied, determine the bridge constant for the measurement system. If SE 250 uV and E, -10 V, estimate the average gauge factor of the strain gauges. For this material, Poisson's ratio is 0.3 and...

1. During a stress-strain test, the unit deformation at a stress of 5,000 psi was observed to be 0.000167 in./in. and at a stress of 20,000 psi it was 0.000667 in./in. If the proportional limit is 30,000 psi, what is the modulus of elasticity? What is the stress corresponding to a strain of 0.0002 in./in.? Would these results be valid if the proportional limit were 18,000 psi? Explain. 2. A steel wire 30 feet long, hanging vertically, supports...

The specimen isn't very thick or thin, so we cannot assume a state of plane strain or plane stress. Thus we expect a fully 3D strain state at any given location in the specimen. For example: 7 a -30 25 -30 6 -42 um/m ( 25 -42c ) e= 1 Assume an isotropic material with Young's modulus of 27 GPa and Poisson ratio of 0.14. Given that a = -2, b = 3, and c = 3, what is the...

A point of the material subjected to plane strain has strains: εx = 120×10-6, εy = 70×10-6 and γxy = 80×10-6. The modulus of elasticity and poisson's ratio of the material is E = 210 GPa and ν = 0.3 respectively. Determine the normal stress along the x axis σx = Answer MPa (rounding to two decimal places).
