State true or False: Poisson’s ratio is negative for Tensile deformation.

A material has Poisson's ratio 0.50. If a uniform rod of it suffers a longitudinal strain of 2×10−32×10-3, then the percentage change in volume is

When a strain gauge is strained in its axial (grid line) direction, its resistance increases as thegrid length increases. Poisson's ratio predicts that the resistance will also change as a resultof transverse deformations. For a positive axial strain (tension), how does the gaugeresistance change as a result of the Poisson effect (increase, decrease, no change)? Pleasediscuss your answer

The slope of the stress-strain curve in the elastic deformation region is ____________*1 pointa) Elastic modulusc) Poisson’s ratiob) Plastic modulus

is the breaking stress same as the ultimate tensile stress?

What is the name for the ratio of stress to strain for a material in the elastic region of deformation?
