) can be expressed asQuestion 3
A solid steel sphere having modulus of elasticity of 200GPa and poission’s ratio of 0.25 is subjected to what hydrostatic pressure (in MPa) so that its volume is reduced by 0.3%.
Question 4
An elastic bar is subjected to a longitudinal direct tensile stress of magnitude σ1. If the volumetric strain in bar due to above loading is half the longitudinal strain, the Poisson ratio of material is
Question 5
A bar of diameter 20 mm is subjected to a tensile load such that the measured extension on a gauge length of 150 mm is 0.08 mm and the change in diameter is 0.0032 mm. The Poisson’s ratio will be ________.
Question 6
Calculate the Poisson’s ratio of the bar material if a tensile force of 350 kN is applied to it which causes its diameter its to reduce by 0.024 mm and length to increase by 0.85. The dimensions of the bar are 600mm x 60mm.
Question 7
Two dimensional stress system on a block made of a material with Poisson’s ratio of 0.3 is shown in fig.
The limiting magnitude of the stress so as to result in no change in length AB of the block is ________ N/mm2.
