Unformatted text preview: max and the major principal stress by I . Derive, using the geometry of Mohrs circle of stress, expressions for the maximum values of direct stress which may be applied to the x and y planes in terms of the three parameters given above. Hint: x = OP 1 = OB BC + CP 1 3.- The direct strains in the directions, a, b, c are -0.002, -0.002, and +0.002, respectively. If I and II denote principal directions find I , II , and ....
