The initial principal stresses at a certa 100 kPa on the vertical plane. Con consisting of a vertical stress of counterclockwise (with respect to the Plot Mohr's circle (1) for the initial Determine (a) the change in magnitu stress, and (c) the change in orientatio the foundation.

The solid shaft is fixed to the support at C and subjected to the torsional loadings and axial load P as shown. a. Determine the torsional shear stress at Point A (50mm from the center) and Point B (on the Surface) b. Determine the absolute maximum torsional shear stress in the shaft. c. sketch the state of stress at point A and draw its corresponding Mohr’s Circle of stress. compute the principal stresses and maximum in-plane stress. T=10.38kN-m

2.18. The stress at a point is defined by the components Oxr = 85 MPa, Oyy= 320 MPa, oz= 100 MPa, Ory =-40 MPa, ơ =50 MPa, ơzx=-20 MPa. Find the three principal stresses, sketch the three Mohr's circles and hence determine the magnitude of the maximum shear stress. yz
