Figure shows a state of plane stress consists of normal stresses σx = 60 MPa and σy = -40MPa; and unknown shear stress, ?xy. The maximum principal stress was determined to be 104.34 MPa. Using Mohr’s circle, determine; the magnitude of the shear stress, the principal plane and the minimum principal stress. Then, sketch the element showing all stresses in its proper orientation, the maximum shear stress, associated normal stress and the orientation of the element. Then, sketch the element showing all stresses in its proper orientation, the stress components acting on the inclined plane AB. Then, sketch the element showing all stresses in its proper orientation

Solid Mechanics

Engineering mechanics is a branch of science that deals with forces causing bulk motion in bodies and the effect that these forces cause on the bodies. Engineering mechanics does not deal with the internal changes that occur on account of these external forces. The internal effects in a body or a material under the action of external forces are studied in a new branch of science called solid mechanics, the strength of materials, or the mechanical behavior of engineering materials.
