The state of strain at a point on a plate is measured using the strain rosette shown in Figure Q1. Due to the loadings, the readings from the gauges gauges give Ea = -60 x 106 mm/mm, & +350 x 10-6 mm/mm, and &c = +300 x 10-6 mm/mm. a) Provide the strain tensor. b) Determine the principal strains and corresponding directions (in degrees). c) Draw a complete strain Mohr diagram with labels. Show the given state of strain, principal strains and their orientations in the diagram. d) Is it possible for both plain stress and plain strain to occur concurrently? Explain.

A certain equiangular strain gauge rosette is made up of three separate gauges. After it has been installed it is found that one of the gauges has, in error, been taken from an odd batch; its gauge factor is 2.0, that of the other two being 2.2. As the three gauges appear identical it is impossible to say which is the rogue and it is decided to proceed with the test. The following strain readings are obtained using a gauge factor setting on the strain gauge equipment of 2.2: Gauge direction 0o 60o 120o Strain * 10-6 +100 -250 +300 Taking into account the various gauge factor values evaluate the greatest possible shear stress value these readings can represent. For the specimen material E = 210 GN/m2 and v = 0.3
