The state of strain on the element has components ε x = -300(10 -6 ), ε y

Question:

The state of strain on the element has components εx= -300(10-6), εy= 100(10-6), γxy= 150(10-6).

Determine the equivalent state of strain, which represents 

(a) The principal strains, 

(b) The maximum in-plane shear strain and the associated average normal strain. Specify the orientation of the corresponding elements for these states of strain with respect to the original element.
