Question 2 (40 Marks): A rectangular strain gage rosette is applied to a point on a steel bridge member as shown. The strains at the point are known to be: εx= 6600 µ; εy= -1650 µ; and γxy = 2640 µ.

Using Mohr’s circle only, determine the strain reading of gage B. Also, draw a deformed element at the maximum shear plane.
