QUESTION 2) The state of strain at point A on the bracket is measured using the strain rosette shown in Figure. Due to the loadings, the readings from the gauges give ɛa=150x10", e-200x10 and Ec=100x106 Determine the in-plane principal stresses at the point and the directions in which \30° they act. 150° a,x Take the modulus of elasticity as E= 80 GPa and Poisson ratio as v= 0.3.

QUESTION 2) The state of strain at point A on the bracket is measured using the strain rosette shown in Figure. Due to the loadings, the readings from the gauges give ɛa-150x10, £v=200x106 and Ec=100x106 Determine the in-plane principal \30° stresses at the point and the directions in which they act. 150° a,x Take the modulus of elasticity as E= 80 GPa and Poisson ratio as v = 0.3.
